<h3>What is a chromosome?</h3>
A chromosome is consist of two chromatids. The two chromatids are joined together by a structure known as the centromere.
The two chromatids of the same chromosome are referred to as sister chromatids.
Chromosomes have 2 arms depending on the location of the centromere. When the centromere is skewed to a particular side, the chromosomes will have longer and shorter arms.
