deoxyribonucleic acid

Deoxyribonucleic acid (DNA) is a large molecule containing human genetic information. It is made up of different bases, phosphate and sugar. The molecule has two strands, which are connected to each other like a ladder and entwine to form a helix. The DNA is part of the chromosomes in the cell nucleuses of the body. It stores genetic information, which is needed to produce new cells, for example.
