Question

Location of centromere in a sub metacentric chromosome

Answer 1

Centromere is a narrow non-stainable area,which join two similar threads or chromatids of a late prophase or metaphase chromosome. The two parts of the chromosome on either side of the centromere are known as arm. They may be isobranchial (equal) or helerobranchial (unequal in length).

Sub-metacentric chromosome: The centromere is sub-median and the anaphasic chromosome appear L-shaped.
