Chromosomes and DNA. Computer artwork of X (pink) and Y (green) chromosomes with an autoradiogram in the background. Chromosomes are a packaged form of DNA (deoxyribonucleic acid). The DNA condenses into chromosomes during cell replication for ease of division and transport into the new cell. Most mammals have one pair of sex chromosomes in each cell. Males have one Y chromosome and one X chromosome,while females have two X chromosomes. Autoradiograms show the order of nucleotide bases (basic building blocks) in a DNA sample | |
