Alright, so here we have two questions.
00:03
So the first question, it says that what are the respective roles of b -5xonuclate and 3 -xonucase activities of dna polymerase 1? so here, the 3 -prime, first let's talk about the 3 -prime to 5 -prime exonuclease activity of dna -polymerase 1.
00:32
So what it does it, it acts for proof reading in dna replication.
00:37
So it recognizes the cross made during the replication and it moves one base pair back and excise the incorrect base and hence helps in it helps in dna repairing.
00:54
Now next is 5 prime to 3 prime exonuclease activity of the of dna polymerase 1.
01:06
So this basically is essential for processing the dna during replication.
01:12
So the activity, it is also called as the nic translation activity.
01:20
Right.
01:21
So it helps in removing rna primers and it allows the replication to proceed ahead on the lagging strand.
01:35
Right.
01:36
Now the next question here, it says that the...
