Nirmala Agarwal. Advertisements: Chromosome: 1. Chromosomes are single physical structure and hereditary traits, which are transmitted through them. 2. The structure of chromosome is best studied at the metaphase, which possesses two chromatids held by a single centromere. Chromatid: 1. Each chromosome consists of two symmetrical strands called chromatids, formed during S-phase. 2. Each chromatid is half of the metaphase chromosome.
â¢ They are both similar in structure to a certain extent because the DNA strand is common to both. â¢ In a single cell, the number of both DNA and chromosomes are similar, but only chromosomes contain histone proteins. â¢ The DNA which is much longer (4.8 cm) than chromosomes (6 Âµm) has a less coiled structure than chromosomes. â¢ The DNA can replicate in its natural form, but the chromosomes have to unwind themselves to attach with transcriptase for the replication. â¢ All cells except red blood cells contain DNA and chromosomes.
