Today we finished the DNA replication chapter.
We discussed the main differences between prokaryotic and eukaryotic chromosomes, and how the ends of eukaryotic chromosomes (telomeres) are repaired by the action of telomerases (three scientists were awarded the Nobel Prize in physiology or medicine, in 2009, because of their research on telomerases).
Among the differences between prokaryotic and eukaryotic DNA replication we mentioned how in eukaryotic chromosomes have multiple replication origins, and in their DNA replication process there are two DNA polymerases and a few proteins that are not found in the prokaryotic DNA replication.
