Biology · Molecular Basis of Inheritance
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The coding strand of DNA in a transcription unit has the polarity of 5' → 3' and its sequence is the same as RNA (except thymine is present instead of uracil). Reason (R): The strand that is referred to as the coding strand does not actually code for anything during transcription. In the light of the above statements, choose the correct answer:
- 1Assertion (A) is false, but Reason (R) is true
- 2Assertion (A) is true, but Reason (R) is false
- 3Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A)✓
- 4Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
Correct answer
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A)
