We have here is draw a diagram of dna replication, label and describe it.
00:06
So we have to first draw a diagram of the dna replication, we have to label it and we'll describe it.
00:11
So the first thing we'll draw is the parental strand from where the dna replication will actually start.
00:18
This is the parental strand.
00:24
And let's say this is the origin of replication from where the replication will start.
00:28
And we'll label this strands 5 prime, 3 prime, 3 prime and.
00:35
5 prime.
00:37
Now dna synthesis will happen from 5 prime to 3 prime direction continuous means there will be no issues there with the help of dna polymerase and that will mean the new strand here or the leading strand will be this in this direction.
00:58
This is the leading strand and these are the basis between the strands, base pairs, the hydrogen bonds between the base pairs this is the lagging strand and these are the fragments known as the okazaki fragments.
01:37
These fragments are produced or synthesized in bits and pieces and they will be joined together later.
01:44
So these fragments are known as okazaki fragments and okazaki fragments are present only in the lagging strand.
01:54
So this one is the lagging strand.
02:01
Now the direction of the lagging strand, if you see this is in 5 prime to 3 prime direction and this is in 3 prime to 5 prime direction.
02:15
So that's why this is the lagging strand.
02:19
These are the base pairs.
02:23
And now the next part of this is the rna primers.
02:30
So there will be rna primers here.
02:34
The green colored parts are rna primers...
