Answer Details
A chromosome consists of two chromatids joined at the centromere. Chromosomes are structures within the nucleus of a cell that carry genetic information in the form of DNA. Each chromosome is made up of two identical sister chromatids, which are joined at the centromere. The chromatids contain the genetic information in the form of genes, which are the units of inheritance. During cell division, the chromatids separate and each daughter cell receives one chromatid, which becomes a new chromosome.
