DNA replication of prokaryotes

Prokaryotic DNA replication is an anabolic process by which prokaryotes duplicate their genomic DNA to transfer it to their daughter cells. DNA replication in prokaryotes especially in E. coli (model … Read more

Helicase vs Topoisomerase (DNA gyrase)

Recently, several studies have found the direct interactions between helicase and topoisomerase. However, several variations were found in their mode of functions. The major differences between helicase and topoisomerase Helicase … Read more
