G0 G1 G2 S
- Quick help Only cell biology Which process is described in the following paragraph? During DNA synthesis, before the enzyme adds the next nucleotide to a growing DNA strand, it checks whether the previously added nucleotide is correctly base-paired to the template strand. If so, the polymerase adds the next nucleotide; if not, the polymerase clips off the mispaired nucleotide and tries again. This is carried out by cleaving the phosphodiester backbone using the enzyme’s 3’-to-5’ exonuclease activity.Replication:- what other enzymes are involved in the initiation phase?- explain the role of primers in this phase- how is the building of the leading strand different from that of the lagging strand?a) Explain how the molecular mechanism of DNA polymerase enhances DNA replication. b) Discuss the characteristic of DNA polymerase 1, Nick translation Proofreading
