Question

Restriction enzymes belong to a class ______ (a) Polymerases (b) Nucleases (c) Endonucleases (d) Isomerases

Answer 1

Endonucleases........

Answer 2

Restriction enzymes belong to class of –‘Nucleases’.  Restriction Endonucleases is the other term for these restricted enzymes.

These recognize the very specific base pair sequence of DNA.

It acts as a defence structure at its place. These restriction enzymes act to split and cut fragment of DNA.

This acts for the genetic functioning and the genetic engineering. These enzymes recognize and bring out specific sequence of nucleotides in the DNA sequence.
