This question asks, which of the following enzymes is not involved in dna replication? primase, dna ligase, rna polymerase, and telomerase.
00:11
Well, let's start off with primase.
00:14
Primase is going to deposit an rna primer in order to begin replication.
00:23
So this will occur once on our leading strand, and this will occur at the beginning of each okazaki fragment on the lagging strand.
00:35
So this will be involved in dna replication.
00:38
Dna ligase will join separate dna strands together.
00:51
So that is whether we're talking about proofreading after we have excised some error that has occurred in our nucleotide sequence.
01:00
That can also refer to our lagging strand when we are going to join our okazaki fragment.
01:08
Together.
01:10
So dna ligase is going to be involved, obviously, in dna replication.
01:14
And then looking at telomerase, well, we know that the telomerase will allow for telomere synthesis or deposits those telomeres at the ends of our dna segment...
