Lecture, chapter 5 - DNA replicaiton

Today we started chapter 5, on DNA replication, and the third stop in our roadmap, on how genetic information is preserved and inherited.

We started a discussion on how DNA is replicated in prokaryotes, including the concepts of replication fork and replisome. We described the role of several enzymes on the process of DNA replication (DNA gyrase, DNA helicase, single strand binding (SSB) proteins, primase, DNA polymerase), and the fact that there are a leading and a lagging strand during the replication process, the latter being extended in bursts forming Okazaki fragments.
