解析 Helicase - begins to uwind the DNA at the origin of replication forming the replication bubble. This will be held open by single stranded binding proteins to allow for the addition of nucleotides to the parent strands toward the replication fork....
DNA replication forks begin forming at the origin of replication (ORI). B DNA replication forks are caused by helicase separating two complementary strands of DNA. C There are two replication forks found in each replicating prokaryotic chromosome. ...
The lagging strand is made of a series of fragments that must be joined together to make a continuous strand. DNA ligase adds nucleotides to the lagging strand. The two strands of original or parental DNA are separated during DNA replication. ...
DNA replication is a process by which a double-stranded DNA molecule is copied into two, identical DNA moleculesScitable
