Question

Match the LIST-I with LIST-II

Choose the correct answer from the options given below:

• A. A-I, B - II, C - III, D - IV
• B. A-I, B - III, C - II, D - IV
• C. A-III, B - I, C - IV, D - II
• D. A-III, B - IV, C - I, D - II

Hint:

Remember the prefixes: \textbf{Meta-} (middle), \textbf{Sub-meta-} (below middle), \textbf{Acro-} (peak/tip), and \textbf{Telo-} (end). This will help you visualize and remember the centromere positions.

Answer 1

The Correct Option is C

Step 1: Chromosome Classification:
Chromosomes are categorized into four types based on centromere position, which defines the 'p' (short) and 'q' (long) arms.
Step 2: Matching Chromosome Types to Centromere Positions:
Match the chromosome types (LIST-I) with their corresponding centromere positions (LIST-II):


A. Metacentric: Centromere is central, creating equal-length arms. Corresponds to III. Centromere in the center.

B. Submetacentric: Centromere is slightly off-center, creating unequal-length arms. Corresponds to I. Centromere slightly off-center.

C. Acrocentric: Centromere is near one end, creating one very short arm and one very long arm. Corresponds to IV. Centromere near one end.

D. Telocentric: Centromere is at the chromosome end (telomere), resulting in only one arm. Corresponds to II. Centromere at one end.

Step 3: Solution:
The matching is: A-III, B-I, C-IV, D-II, which is option (C).
