Which among the following is incorrect about chromosomes? Correct Answer In acrocentric chromosomes, centromere is present in the end of the chromatids

Chromosomes are rod shaped structures that condenses together when the cell is about divide. Chromosomes are composed of DNA, RNA and proteins which act as repository for inheritance. Kinetochores are disc like structures that are present on the sides of centromeres. In telocentric chromosomes, centromere is present in the end of the chromatids.
