Match List-I with List-II regarding the types of chromosomes based on the position of the centromere. List-I List-II (A) Metacentric (i) Centromere situated close to its end (B) Sub-metacentric (ii) Terminal centromere (C) Acrocentric (iii) Centromere slightly away from the middle (D) Telocentric (iv) Middle centromere forming two equal arms Choose the correct answer from the options given below:
Options
- A(A)-(iv), (B)-(i), (C)-(iii), (D)-(ii)
- B(A)-(iv), (B)-(iii), (C)-(ii), (D)-(i)
- C(A)-(iv), (B)-(iii), (C)-(i), (D)-(ii)
- D(A)-(iii), (B)-(iv), (C)-(i), (D)-(ii)
Correct answer
C. (A)-(iv), (B)-(iii), (C)-(i), (D)-(ii)
Step-by-step solution
Based on the position of the centromere, chromosomes are classified into four types: Metacentric chromosome: The centromere is located in the middle, forming two equal arms of the chromosome. Hence, (A) matches with (iv). Sub-metacentric chromosome: The centromere is located slightly away from the middle of the chromosome, resulting in one shorter arm and one longer arm. Hence, (B) matches with (iii). Acrocentric chromosome: The centromere is situated close to its end, forming one extremely short and one very long
