Nucleic acids and protein synthesis

Abstract

The chromosomes found in the nucleus of every cell are responsible for the development of that cell and for the control of the behaviour of the mature cell. The chromosomes seem to consist primarily of the nucleic acid known as deoxyribonucleic acid or DNA. The DNA carries the ‘Plans’ for the structure of every protein molecule manufactured by the cells. Since the proteins include the enzymes and since the enzymes are responsible for the manufacture of all non-protein substances in a cell, the DNA is in the end responsible for the manufacture of all substances made by each cell.
