Chromosome. Computer artwork of a human chromosome showing the telomeres (green) and centromere (red). Chromosomes are composed of deoxyribonucleic acid (DNA) that contain sections,called genes,which encode the body's genetic information. Telomeres protect the ends of the chromosome and play a key role in cell aging. Each chromosome consists of two chromatids joined at their centres by the centromere,which is involved in cell division | |
