Transcript

00:01 Hi, in this question we have to talk about the enzymes.

00:05 We are given several, you can say, some parts of this question.

00:09 In first part, we are asked about the nucleotide that joins in the sequence complementary to the dna template.

00:17 So i must tell you that if we talk about this enzyme, it will be called as the dna polymerase.

00:26 And if we talk about this dna polymerase, you must understand that this enzyme is very much important to add the nucleotides to an existing nucleic acid strand.

00:37 And it cannot add these nucleotides without an, you can say, existing nucleic acid.

00:45 And that is why it will require a primer.

00:50 Fine.

00:51 This is the first part of the question.

00:53 The second part of the question asks about the enzyme that joins the nucleotides so that the sequence is complementary to the parental strand.

01:03 And to this, the answer is the dna ligase.

01:08 Okay, so we'll write dna ligase over here as answer.

01:13 If we talk more about this, then this dna ligase is important to form the phosphodiceter bond.

01:22 This phosphodicell bone is very important to bond the strands of the dna.

01:28 Yes, so it will connect the two strands we can say of the double stranded dna.

01:37 Okay.

01:37 And also you must understand that it will also link the okazaki fragments.

01:44 What are these okazaki fragments? these okazaki fragments are the lagging strand.

01:52 Why lagging strand? because you have to attach the primer again and again.

01:58 Okay? because the fork that is formed during the replication of dna has to be opened again and again by the helicase enzyme.

02:06 Okay.

02:07 So this is the dna like case.

02:08 That is the second part of the question.

02:10 Let us just mark it as the answer of the second part.

02:14 And the first part answer is the dna polymerase that we have marked over here...
