Question and Answer

The proces of transformation is not affected by which of the following enzymes?
A. Dnase ,B. Rnase
c. Peptidase , D. Lipase
(A) A,B
(B) A, B, C, D
(C) B, C, D
(D) A, B, C

Answer

Answer: c
(c) : Transformation is a phenomenon by which DNA isolated from one type of cell when introduced inot nother type is able to give some of its properties ot the latter. In 1944, Avery, McCarty and MacLeod dicovered that protein-digesting enzymes (proteases)and RNA -digesting enzymes (RNases) did not affect transformation, so the transforming substance was not a portein or RNA. Digestion with DNase did inhibit transformation. They concluded that DNA is the hereditary material.
