Hi, in the first part of this question we need to discuss about two classes of dna lesions which are first is the cyclobutane pyromidine and second is the six four photo products both of these just chart dna structure introducing kings and and thereby impeding transcription and replication process.
01:02
Now move to the next part of this question.
01:07
In the next part of this question we need to tell what are the two dna enzymes that take participates in catalysis.
01:18
So first is the dna nucleases.
01:26
So these catalyze the cleavage of the phospho diastases.
01:30
Bond these enzymes play crucial role in various dna repair processes second enzyme is the enzyme photo lies so this enzyme involves in repair mechanism now move to the next part of this question in the third question we need to tell what is plasmid so plasmid or we can say that vactor transformation, it is the process by which exogenous dna is transferred into host cell.
02:40
It implies uptake of dna into the bacterial cell or yeast cell or plant.
02:57
Cell.
02:58
Now in this question we need to discuss about plasmid.
03:04
So a plasmid, it is a small circular, double -stranded tna molecule that is distinct from a cell's chromosomal dna...
