In the year 1963, the two enzymes responsible for restricting the growth of bacteriophage inEscherichia coliwere isolated. They are
Options:
Answer:
D
Solution:

Methylase enzyme adds methyl groups to the bacterial DNA in order to prevent the destruction of its own DNA by restriction enzymes. This prediction was confirmed in 1963 by Stuart Linn and Arber when they isolated the enzyme methylase which was previously known as modification enzyme.
