At the beginning of DNA replication there are two strands of DNA nucleotides.
Two - the leading strand and the lagging strand.
base pairs are broken apart
The three main steps in the process of DNA replication are initiation, elongation and termination. Initiation is the beginning of the process. During elongation new DNA strands are formed and in termination replication ends.
DNA replication duplicates the DNA strands. This process is accompanied by various enzymes such as DNA polymerase, Helicase, Topoisomerase.In labs they are constructred by Polymerase chain reaction(PCR).
It would most likely be directly involved in replication.
Conservative (In which both parental strands reassociate) and Dispersive (In which daughter strands have mixture of parent DNA) both are not the methods of DNA replication
replication fork
hold the strands apart
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
Assuming this is regarding DNA replication or transcription, the enzyme helicase separates the two strands.
in a direction opposite to that of the replication fork
