Begin with the End in Mind The theme or “big ideas” for this PBL: The student will focus on Mendelian genetics and the process of protein synthesis. Students will be introduced to the structure and function of nucleic acids and the process of replication, transcription, translation, and genetic variation.
TEKS/SEs that students will learn in the PBL: (6) Science concepts. The student knows the structures and functions of nucleic acids in the mechanisms of genetics. The student is expected to: (A) describe components of deoxyribonucleic acid (DNA), and illustrate how information for specifying the traits of an organism is carried in the DNA; (B) explain replication, transcription, and translation using models of DNA and ribonucleic acid (RNA); (C) identify and illustrate how changes in DNA cause mutations and evaluate the significance of these changes; (D) compare genetic variations observed in plants and animals; (E) compare the processes of mitosis and meiosis and their significance to sexual and asexual reproduction; and (F) identify and analyze karyotypes.
Key performance indicators students will develop in this PBL: The learner will be able to demonstrate DNA replication and protein synthesis and be able to explain each step in the process. Students will also be able to distinguish phenotypic and genotypic ratios in monohybrid and dihybrid crosses. The students will be able to communicate the impact of frameshift mutations on protein synthesis. 21st century skills that students will practice in this PBL: www.21stcenturyskills.org Team-work, responsibility, and productivity © 2008 Transformation 2013

Team-Building Activity It is important that teachers provide team-building activities for students to help build the 21st Century Skills that are necessary for success in the workforce. Team-building helps establish and develop a greater sense of cooperation and trust among team members, helps students adapt to new group requirements so that they can get along well in a new group, serves to bring out the strengths of the individuals, helps identify roles when working together, and leads to effective collaboration and communication among team members so that they function as an efficient, productive group. Our students are often not taught how to work in groups, yet we assume that they automatically know how. Use team-building activities with your students so that you can see the benefits which include improvement in planning skills, problem solving skills, decision making skills, time management skills, personal confidence, and motivation and morale. Balloon Juggle & Sort Balloon games can be used as party games, fun fillers, energizers, icebreakers, or for longer trust-building, team-building, and therapeutic sessions. Have each of the participants inflate two balloons. Assign the participants to groups of three (6 balloons per group). Challenge participants to keep all balloons in the air. This gets the group moving and cooperating. Once they've got the hang of it, make it harder by adding in more balloons or placing restrictions e.g., no hands to keep balloons up. Ask participants to keep juggling the balloons, but to sort them into colors (works best with large groups). Debrief with the participants using the following set of questions: Was anyone frustrated during the activity? Why is teamwork important for the success of this activity? Did everyone play an equal role in the group’s success? If you could do the activity again, what would you do differently? The same?

Strawberry DNA Lab The native British wild strawberry is a "diploid" - it has two sets of chromosomes, as in humans or peas. The most commonly cultivated strawberry, Fragaria ananassa, is an octoploid with eight sets. This makes it a good candidate for demonstrating DNA extraction - with eight copies of each gene in the strawberry genome, strawberries are packed full of it. How some strawberries evolved from diploids to octoploids is part of the story that people are trying to unravel. The strawberry, it turns out, has a long and complicated family history. "The cultivated strawberry is interesting from a genomic perspective, because it's a polyploid hybrid species." Many people are surprised to find out that strawberry growers plant bare-root plants rather than seeds. The reason is every strawberry seed contains different genetic material, the product of a myriad of potential gene combinations because the genetics of strawberries are so diverse. For strawberries, the mother plant puts out runners (called daughter plants) that are essentially identical to her, which in turn also put out runners. The major varieties of strawberries grown in Florida are Sweet Charlie, Camarosa, and the Oso Grande.
One of the reasons strawberries work so well is that they are soft and easy to pulverize. Also, ripe strawberries produce enzymes (pectinases and cellulases) which aid in breaking down the cell walls. Most interestingly, strawberries have enormous genomes. Materials
Mild Shampoo (Containing Laurel sulfate- SDS)
Zip lock bags (double bags)
A few pinches of NaCl
Papain (Meat tenderizer). This is an enzyme that destroys proteins that would interfere with the DNA extraction.
Frozen or fresh strawberries or raspberries - about 1 to 2 cups
Ice
Corning tubes
Beaker or plastic cup
Transfer Pipets

Cheese cloth/Melitta coffee filters are an alternative
Rubber bands
Eppendorf tubes (Microcentrifuge tubes)
Microcentrifuge
Ice cold ethanol (97%)
Tris EDTA solution
Water bath at 55oC
Procedure for Extraction 1.
Place several strawberries in a double zip lock bag. Use the top of the Corning tube to mash the strawberries in the bag. This should produce a homogenate of strawberries. This is a mechanical breakdown of the cell wall and structure.
2.
Add 15 mL of the extraction buffer to the bag.
3.
Mush again for one minute. This is the chemical portion of the extraction procedure to lyse the cell membranes to release the DNA
4.
Put bag into the hot water bath at 55oC – 60oC. Heating helps to maximize the reaction to make sure that DNA is released. The temperature is critical to this step. DNA is denatured at temperatures near 80oC.
5.
Remove and put bag into the ice chest.
6.
Put cheesecloth over the top of a beaker or plastic cup. Hold with a rubber band around the top.
7.
Filter through cheesecloth in a funnel into beaker. Use the top of the Corning tube to push through the mesh of the cheese cloth. Collect the filtrate. When you are finished, squeeze the cheesecloth to get the remainder of the extract or lysate.
8.
Pour filtrate into a plastic tube. Fill the tube to about ½ the volume.
9.
Use the transfer pipet to drip alcohol slowly down the sides of the tube, while holding the tube at approximately an angle of 45o. Try to make a clear and undisturbed layer of alcohol to float on the lysate. The line between the two layers is called the interface.
10. At the interface, you will see the DNA precipitate out of solution and float to the top. You may spool the DNA on your glass rod. You should see strands of DNA winding around the DNA. 11. Collect the DNA which is in the upper layer of the alcohol with the transfer pipet. Empty the air and then aspirate the DNA from the tube. Make sure that you do not disturb the layers.

Explanation
The detergent in the shampoo helps to dissolve the phospholipid bilayers of the cell membrane and organelles. The salt helps keep the proteins in the extract layer so they aren’t precipitated with the DNA.
DNA is not soluble in ethanol. When molecules are soluble, they are dispersed in the solution and are therefore not visible. When molecules are insoluble, they clump together and become visible. The colder the ethanol, the less soluble the DNA will be in it yielding more visible “clumping.” This is why it is important for the ethanol to be kept in a freezer or ice bath.
Preparation of DNA for Isolation and Purification 12. Put the DNA in an Eppendorf (microcentrifuge tube 1.5mL). 13. Spin the Eppendorf (microcentrifuge tube) for two minutes. 14. Pour off the liquid in the tube. This leaves a pellet in the bottom of the tube which is DNA. 15. Add 25 – 50 ul of Tris EDTA Buffer to the Eppendorf tube. Resuspend the pellet of DNA in the buffer. This makes the DNA go into solution Preparation of samples of Strawberry DNA for electrophoresis (extension activity for PAP) 16. Take 15 ul of the DNA solution and put it in a new microcentrifuge 17. Add 2 ul of the loading dye to this tube 18. Take another 15 ul of the DNA solution and put into a new microcentrifuge tube for analysis

Ona Oompah (from#4) divorces Otis and marries Otto. Otto has an orange face. What is the probability that Ona and Otto's children will have orange faces? 7. Oompahs can have red, blue or purple hair. Purple hair results from the heterozygous condition. Make a "key" showing the genotypes and phenotypes for hair color. Is this an example of codominance or incomplete dominance? Justify your answer. 8. Orville Oompah has purple hair and is married to Opal Oompah who brags that she has the bluest hair in the valley. How many of Opal's children will be able to brag about their blue hair also? 9. One of Opal's children is born with shocking red hair. Is Orville the father of this child (show the square to prove your answer)? But wait, Opal swears she has been faithful and claims that the hospital goofed and got her baby mixed with another. Is this a plausible explanation? Show the square to prove your answer. 10. Olga Oompah has red hair and marries Oliver Oompah who has blue hair. They have 32 children. What color is their children's hair? 11. Olivia Oompah is married to Odo Oompah and they both have purple hair. What color hair and in what proportion would you expect their children to have? 12. In the land of Oompah, blue hair is highly valued; blue haired Oompahs even get special benefits. Oscar Oompah has purple hair but he wants to find a wife that will give him blue haired children.

A Chromosome Study In this activity, you will create a karyotype from a page of mixed chromosomes. Karyotypes are created by matching homologous pairs and numbering them from largest to smallest. Abnormalities, such as extra or deleted chromosomes can then be diagnosed. Pictured chromosomes will be used for this model rather than real chromosomes, but the process is the same for real chromosomes extracted from cell or fetal samples. Two karyotypes will be created; the first represents a normal human karyotype of a male or a female, the second represents and abnormal karyotype. You will then compare and diagnose the abnormality present in the patient of the second karyotype.
Normal Human Karyotype Examine the page marked "normal". These chromosomes are actually enlarged photographs of what is seen through a microscope. Note that the sex chromosomes have been labeled for you as either X or Y chromosomes. They have been marked this way to indicate these are the sex chromosomes. Cut out each chromosome with scissors, to make it go faster, cut them out as squares rather than trying to cut around the margin of each chromosome. Prepare a karyotype of these chromosomes. A karyotype is a pattern or picture of chromosomes from one cell grouped into pairs and organized by size. --Pair up each of the chromosomes with its homologous pair, use the size and markings on the chromosomes to determine pairs. Temporarily put the two unshaded chromosomes aside. --On a blank paper, arrange the chromosome pairs from largest to smallest and number them. You numbers should range from 1(largest) to 22(smallest). Put the sex chromosomes last, this is pair #23. Glue or tape the chromosomes to the paper in the correct order. Sex chromosomes determine the sex of the individual. A female develops when the sex chromosomes match--XX . A male develops if the two sex chromosomes are unmatched--XY. (These chromosomes are unshaded on your karyotype) 1. How many total chromosomes are present in this karyotype? _____________ 2. How many chromosomes are present in each cell of this human? _____________ 3. Does your karyotype represent a male of a female? ________________ 4. Chromosomes that are NOT sex chromosomes are called autosomes. How many total autosomes are present in your normal karyotype? ______________ Body cells are called somatic cells. Somatic cells include the skin, liver, muscle, stomach and other bodily cells. The karyotype you prepared is from a somatic human cell. The term diploid chromosome number refers to the number of chromosomes in a somatic cell. The diploid

Last Updated: 9/25/08
number varies from species to species, however it does not differ from somatic cell to somatic cell within the same organism. To find your diploid number, simply count the number of chromosomes in your karyotype. The diploid chromosome number is also called the 2n number. 5. What is the diploid chromosome number for your karyotype? _____ 6. What is the 2n chromosome number for your karyotype? ____ The HAPLOID CHROMOSOME NUMBER refers to the number of chromosomes in an organisms sex cells. Sperm in males, eggs in females. The haploid number, or 1n number is always -half- that of the diploid number. 7. What would the haploid chromosome number for your karyotype be? ____ Abnormal Human Karyotype --Examine the page marked "Abnormal". Look at the top corner, what Set do you have?____ --Prepare a second karyotype as you did the first. In this karyotype, you will discover an abnormality in the chromosome number. Finding incorrect chromosomes numbers in human somatic cells of an unborn baby alerts doctors to the fact that their child is abnormal and will be born with birth defects. *If the unborn has an extra number 13 chromosome, it it born with Patau syndrome. An extra chromosome 18 results in Edward syndrome. An extra chromosome number 21 results in Down Syndrome. A missing sex chromosome results in an X0 offspring who has Turner's syndrome. An extra X chromosome results in Klinefelters syndrome (XXY). 8. How many chromosomes are present in the abnormal karyotype: ________ 9. What is the diploid chromosome number for this karyotype: _________ 10. Which chromosome pair is abnormal? __________ 11. What syndrome does this unborn have? ____________ 12. What sex will the unborn child be? _____ Analysis: 13. Define the following terms: Somatic Cell Karyotype Diploid chromosome number Autosome

Teacher Key to the Karyotype Preparation: There are enough karyotype sheets, that students can have different ones. For the normal section. Use Normal Girl and Normal Boy sheets. For the abnormal, there are 4 sheets, so again each group can have a different one. Sheet A = Down Syndrome Sheet B - Klinefelter Syndrome (XXY) Sheet C - Edward Syndrome (extra chromosome 18) Sheet D - Patau Syndrome (extra chromosome 13) Do NOT give students the abnormal sheets until the normal one is finished. This will prevent students from getting chromosomes from both sets mixed up. This Lesson generally takes 2 class periods. 1st day - go over the lab and do the "normal" karyotype. 2nd day, do the abnormal karyotype.
