Chromosome. Coloured scanning electron micrograph (SEM) of a chromosome. Chromosomes, which consist of two identical chromatids joined at a centromere, are comprised of deoxyribonucleic acid (DNA) coiled around proteins. This complex is known as chromatin. This is an acrocentic chromosome, the centromere is near one end of the chromosome (bottom) giving two very short arms and two long arms. DNA contains sections, called genes, which encode the body's genetic information, determining each cell's structure, function and behaviour. Magnification: x19,400 when printed 10 centimetres wide.
