Question

Match the Column-I with Column-II and select the correct option.
Column-I Column-II
a) Metacentric (i) Centromere slightly away from the middle of chromosome
b) Sub-metacentric (ii) Centromere at the tip
c) Acrocentric (iii) Centromere in the middle of chromosome.
d) Telocentric (iv) Centromere near the end of chromosome.

• A. a-iii, b-i, c-iv, d-ii
• B. a-iv, b-ii, c-iii, d-i
• C. a-ii, b-iii, c-iv, d-i
• D. a-iii, b-i, c-i, d-iv

Hint:

When dealing with chromosome types, remember: - Metacentric has the centromere in the middle. - Sub-metacentric has the centromere slightly off-center. - Acrocentric has the centromere near the end. - Telocentric has the centromere at the tip.

Answer 1

The Correct Option is A

Step 1: Understanding the question.
The question asks us to match the items from Column-I with their corresponding items from Column-II. Each chromosome type is associated with the position of the centromere. Let’s go through each option.
Step 2: Analyzing the options.
(A) a-iii, b-i, c-iv, d-ii: This matches the following: - Metacentric (a) — Centromere in the middle of the chromosome (iii) - Sub-metacentric (b) — Centromere slightly away from the middle (i) - Acrocentric (c) — Centromere near the end of the chromosome (iv) - Telocentric (d) — Centromere at the tip (ii) This option matches the correct locations of the centromere for each chromosome type.
Step 3: Conclusion.
The correct answer is (A) a-iii, b-i, c-iv, d-ii, as this option correctly matches the centromere positions with the chromosome types.
