Assertion : The uptake of DNA during transformation is an acitve, energy requiring process.
Reason: Transformation occurs in only those bacteria, which posses the enzymatic machinery involved in the active uptake and recombination.

A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion.

B

If both the assertion and reason are true but the reason is not a correct explanation of the assetion

C

If the assertion is true but the reason is false

D

If the both the assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
a

a) Transformation does not involve passive entry of DNA molecules through permeable cell walls and membranes. It does not occur 'naturally' in all species of bacteria, only in those species possessing the enzymatic machinery and involved in the active uptake and recombination processes. Even in these species, all cells in a given population are not capable of active uptake of DNA. only competent Cell, which posses a so- called competence factor are capable of serving as recipents in transformation.
