DNA pink light clip.  DNA is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the growth and reproduction of all known organisms. The abbreviation DNA stands for deoxyribonucleic acid.  DNA is made up of four building blocks called nucleotides.  These are abbreviated as A, C, G, and T.  The order of these nucleotides in a DNA molecule forms a code, known as the DNA sequence. This specifies the instructions for building and maintaining an organism. These instructions are read and used by the cell to make proteins, which are the building blocks of the cell.
