WebApr 2, 2024 · Figure 20.21. 1: The replication of DNA. Replication occurs by means of partial unwinding of the two strands accompanied by synthesis of a new strand complementary to each of the originals. [1] A rather complex mechanism exists for DNA replication, involving many different enzymes and protein factors. WebThis session will explain how DNA is replicated prior to cell division. In this process, DNA polymerase uses an original strand as a template to create a new daughter strand of DNA. Polymerization occurs in the 5’ to 3’ direction, creating a new strand that is anti-parallel to the original. Polymerization begins at a specific DNA sequence ... did kathy bates win an oscar for miseryWebAug 23, 2024 · As replication begins and the DNA strands separate at the fork, many molecules of single-stranded DNA-binding protein (SSB) bind to and stabilise the separated strands, and DNA gyrase (DNA topoisomerase II) relieves the topological stress caused by the unwinding reaction before the fork. did kathy hilton quit housewives
