Harvard dna replication fork
WebDNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in … WebChapter 1: DNA Replication and Replication Stress. The core of the replisome at a replication fork is the replicative helicase known as CMG (Cdc45-MCM-GINS), which unwinds the double-strand DNA to allow replication. The CMG needs to be unloaded from DNA upon the completion of DNA replication. Xia summarized the recent progress in …
