Genetic research, conceptual computer artwork. The X (left) and Y (right) chromosomes (red/white) are the sex chromosomes. Men have an XY chromosome combination, while women have the XX combination. Banding patterns identify the 23 chromosome pairs. Chromosomes, found in cell nuclei, contain DNA (deoxyribonucleic acid). DNA is a helical molecule that is shown down the right edge and along the bottom edge as two twisting strands of letters. The four letters are used to represent the four nucleotide bases of DNA: A (adenine), G (guanine), C (cytosine) and T (thymine). This base sequence varies, making up a unique genetic code. Part of a ribonucleic (RNA) molecule is at top left.
