Phosphorylation process in dna replication
WebOnce activated, these kinases target multiple biological processes, including the repression of late-firing replication origins, cell cycle progression, the production of deoxynucleotide triphosphates (dNTPs), the transcription of DNA damage response genes and finally the functional integrity and restart of stalled or damaged replication forks. 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 the 5' … DNA replication: Process during which a double-stranded DNA molecule is copied …
