Key Takeaways

KEY TAKEAWAYS

• Proteins are based on amino acids and have several different structures: primary, secondary, tertiary, and quaternary. • Protein synthesis starts with transcription of DNA into messenger RNA. It then proceeds to the ribosome with translation into proteins. • There are many post-translational modifications that can happen to the preprotein that is originally made, resulting in a proteome that is many times greater than the genome. • Enzyme speed molecular reactions by lowering the activation energy or the energy of the transition molecules. • There are several protein detection techniques, some of which use immunochemistry, while others use separation and detection techniques that are not based on immunology.
