DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Introduction. DNA is the molecule which controls the synthesis of proteins. Proteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities. Thus DNA is able to exert a controlling influence over the whole cell and ultimately, the whole organism.The segments of DNA which hold the key to this control are the genes.roteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities.
