Question

Name the enzymes 'P' and 'Q' that are involved in the processes given below.
a.) Enzyme P-Exonuclease and Enzyme Q-Permease
b.) Enzyme P-Exonuclease and Enzyme Q- Ligase
c.) Enzyme P-Endonuclease and Enzyme Q- Permease
d.) Enzyme P-Restriction endonuclease and Enzyme Q-Ligase

Answer 1

Answer:

(b).is the correct answer

Answer 2

Answer:

The enzyme P is restriction endonuclease and the enzyme Q is ligase.

Option D

Explanation:

Here, in the schematic diagram, we can see that enzyme P is cutting the 1st DNA marked in blue in the insides of the DNA. This means it is not an exonuclease.

So, it’s a restriction endonuclease that cuts the DNA in perfect places with specific DNA nucleotide sequences. The enzyme Q is seen to join the DNAs together. So, it is ought to be enzyme Ligase which can join two pieces of DNA.
