The molecule abbreviated as DNA (Deoxyribonucleic Acid) contains the hereditary information that directs the structure of each cell and its metabolism. DNA is a long molecule that contains each person's unique genetic code. It holds the instructions for building the proteins that are essential for our bodies to function. DNA molecules are made of two twisting, paired strands, often referred to as a double helix. Each DNA strand is made of four chemical units, called nucleotide bases, which line up in a specific order and form the instructions in the genetic code.
