AIIMS 2019 Botany Bacterial Transformation Assertion Reason Question
Assertion: The uptake of DNA during transformation is an active, energy requiring process. Reason: Transformation occurs only in those bacteria, which possess the enzymatic machinery involved in the active uptake and recombination.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option A is correct because both the assertion and reason accurately describe the process of transformation in bacteria. The uptake of DNA during transformation is indeed an active process that requires energy, and it occurs only in bacteria that possess the necessary enzymatic machinery for DNA uptake and recombination, thus making the reason a valid explanation for the assertion.
Option B is incorrect because the reason does explain the assertion. Option C is incorrect as both statements are true, and option D is false since both the assertion and reason are valid. Understanding transformation is crucial as it highlights the mechanisms of genetic exchange and adaptation in prokaryotic organisms.
