What are the components of DNA replication?
There are four basic components required to initiate and propagate DNA synthesis. They are: substrates, template, primer and enzymes.
What is the role of Primase in DNA replication quizlet?
What is the role of primase is the process of bacterial DNA replication? To synthesize short RNA primers, providing the DNA polymerase with a free 3′-hydroxyl group at the site of dNTP addition based on the template sequence. To unwind the double-stranded DNA into single-stranded DNA.
Why is Primase necessary during DNA replication?
A primer must be synthesized by an enzyme called primase, which is a type of RNA polymerase, before DNA replication can occur. The synthesis of a primer is necessary because the enzymes that synthesize DNA, which are called DNA polymerases, can only attach new DNA nucleotides to an existing strand of nucleotides.
What happens after DNA replication?
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
