Hello students, in this question we have to describe the process of dna replication for the leading strand.
00:07
So let's start our answer the dna replication.
00:15
This is the process by which the dna duplicates itself and it occurs in the cytoplas of procarriots and in the nucleus of ucarriots.
00:55
And it takes place during the synthesis phase of cell cycle in the eukaryotes.
01:05
The process of dna replication, it begins at the specific sequence on the dna, which is origin of replication.
01:34
The process of dna replication, this is a semi -conservative, and this is because the daughter dna molecule, it consists of one parental strand, which is the original sand and one newly formed stand.
02:16
Because of the presence of old one and new one stand in the dna of the daughter, so this process is semi -conservator.
02:26
And the process is also semi -disc conservator, semi -disc continuous.
02:41
This is because the leading stand, this is synthesized continuously in the direction of 5 -2 -3 -d7.
02:54
Direction but the lagging stand this is synthesized discontinuously in the direction of 5 -2 -3 -dash this was continuous and this is discontinuous and the synthesis of dna on the lagging stand it takes place by the formation of small dna fragment which is okazaki fragment on the lagging stand and the enzymes involved in this reaction are.
