Vedclass · Answer

(A) Transformation is a process where a bacterium takes up naked $DNA$ from its environment. This process is not a passive diffusion of $DNA$ molecules through the cell wall and membrane.It is an active,energy-requiring process that occurs only in specific bacteria that possess the necessary enzymatic machinery for active uptake and subsequent recombination of the $DNA$ into the host genome.Even within a population of such bacteria,only 'competent' cells,which express specific competence factors,are capable of performing this uptake.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for why the process is active.

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