Question

In metacentric chromosomes:

• A. Centromere is located at one end so that there is only one arm.
• B. Centromere is non-centrally located so that one arm is longer than the other.
• C. Centromere is centrally located so that the two arms are of equal length.
• D. Centromere is found at the end so that one arm is very short and the other is long.

Answer 1

The correct option is C Centromere is centrally located so that the two arms are of equal length.

Centromere is the primary constriction present in the chromosome which divides the chromosome into two arms. In metacentric chromosomes, this centromere is exactly at the mid-point. Due to which, the two arms will be of equal length and the chromosome resembles the alphabet, 'V'.
