Explanation:
Detailed explanation-1: -There are four basic components required to initiate and propagate DNA synthesis. They are: substrates, template, primer and enzymes.
Detailed explanation-2: -DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. During DNA replication, DNA helicases unwind DNA at positions called origins where synthesis will be initiated.
