Question

Assertion (A): Some experts believe that there must be more than 30,000 genes in human genome.
Reason (R): Unreliability of in silico gene prediction is responsible for reporting lesser number of genes in human genome.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

In Assertion and Reason type questions, try to establish a clear link between the two statements before reaching a conclusion.

Answer 1

The Correct Option is A

Assertion (A): Early human genome estimates suggested over 30,000 genes due to perceived system complexity. However, subsequent progress revealed a lower actual gene count than initially projected. Reason (R): This explanation is accurate as *in silico* gene prediction methods are inherently unreliable, particularly for non-coding regions and shorter genes, leading to discrepancies between predicted and observed gene numbers. Explanation: Both statements are true, and Reason (R) effectively explains Assertion (A), making (A) the correct choice.
