I have been asked this question in an interview.

The query is from Cell in portion Cell : The Unit of Life of Biology – Class 11

Answer 1

Right answer is (d) In acrocentric chromosomes, centromere is present in the end of the chromatids

Easiest explanation: 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.
