Chromosomes with telomeres. Computer artwork of human chromosomes showing the telomeres (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. As cells replicate and age the telomere steadily shrinks. When the telomere reaches a certain length the cell stops dividing and dies | |
