Chromosomes are structures in the nucleus of a cell and are composed of long strands of deoxyribonucleic acid (DNA). In 1953, two scientists, James D. Watson and F.H.C. Crick, proposed a model of the structure of the complex DNA. They described the molecule as a double helix or spiral, composed of nucleotides. Each nucleotide is composed of a phosphate unit joined to deoxyribose, a five-carbon sugar and a nitrogen-containing base. The DNA molecule is a double strand of possibly thousands of nucleotides bonded by synthesis in a cell.
