AIIMS 2019 Botany Chromosome Banding Assertion Reason Question
Assertion : The banding pattern of the chromosome can be studied by dyes as quinacrine, mustard dye of Giemsa.
Reason : These patterns are used for finger printing to study even genetic defects.
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 are true: the banding pattern of chromosomes can indeed be studied using dyes such as quinacrine and Giemsa, and these patterns are utilized in genetic fingerprinting to identify genetic defects. Option B is incorrect because the reason does correctly explain the assertion, while options C and D are incorrect as they assert that either the assertion or reason is false, which is not the case. Understanding chromosomal banding patterns is crucial in cytogenetics for diagnosing genetic disorders and studying chromosomal abnormalities.
