Chromosomes,computer artwork. Chromosomes,which consist of two identical chromatids joined at a centromere,are composed of deoxyribonucleic acid (DNA) coiled around proteins. There are 46 chromosomes in most cell nuclei in a human body; 22 pairs and a gender-determining pair. DNA contains sections,called genes,that encode the body's genetic information,determining each cell's structure,function and behaviour | |
