• Prokaryotic DNA is usually circular with few exons and introns. • In prokaryotes, the transcription and translation occur at the same time. • Eukaryotic DNA is linear and located in the nucleus. • Gene expression in prokaryotes happens when entire operons are expressed or not expressed. • Gene expression in eukaryotes is similar to prokaryotes but involves different activators and repressors. • Gene mutations are of different types that can be serious or not very serious. • Many serious mutations become dangerous because of an inability to correct the mutation, as is seen in certain diseases.
