In order to answer this question, let's talk about dna replication, okay? so it's just going to the following proteins in the general order in which they are required in the dna replication and give an explanation of the word in the process in one sentence.
00:12
So the first one is going to be, you're going to have here the dna helix.
00:21
This here, dna helix is going to open the dna strand.
00:28
It is going to separate both strands, okay? then once both the stands are separated, you're going to have the single strand.
00:35
Stranded binding proteins and these proteins are going to hold or are going to keep the two strands the two parental strands of dna open so they don't collapse again okay so once you have a your your origin of replication opened you're going to have something like this for example your dna helicase is going to be opening in this direction for example your dna helicase okay you have here a single stranded binding proteins that are going to to hold these two strands away from each other.
01:19
Once your helicases keep opening to the right, it is going to find some super coils here.
01:28
Okay, and your dna helicase cannot open these super coils here.
01:32
So in order for your dna helicases to keep separating both strands, you require another enzyme that is called toposomerase.
01:41
Let me see here, okay.
01:45
Gyrease for toposomeres.
01:50
And the yellow going to relieve super coils.
01:57
They are going to relax these super coils so your dna helipases can continue opening these strands or your dna okay.
02:09
After this you're going to have well you know that polymerase 3 is going to polymerize the new strand right so this dna polymerase 3 in order to start polymerizing it requires a short segment of rna okay that is called a primer and this primary and this primary is placed by an enzyme called primis...
