Human chromosomes. Coloured scanning electron micrograph (SEM) of pairs of human chromosomes. One chromosome of each pair has replicated during cell division to form an identical copy,or chromatid. Chromosomes are present in the nucleus of every cell of the body. They consist of genetic material,DNA (deoxyribonucleic acid),in association with proteins. Most human cells contain 46 chromosomes,23 inherited from the mother and 23 from the father. Diagnostic techniques are capable of identifying chromosomes that carry regions of DNA associated with genetic disease. Magnification: x4700 at 5x7cm size | |
