Abstract
Abstract All cells contain both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Most of the DNA is located in the nucleus and in the mitochondria, whereas most of the RNA is in the cytoplasm, and more precisely in subcellular organelles involved in protein synthesis. DNA contains purine bases, adenine (A) and guanine (G), and pyrimidine bases, thymine (T) and cytosine (C). The RNA structure differs from that of DNA by two features: the sugar unit is ribose and not deoxyribose and thymine is replaced by uracil (U). DNA stores genetic information in all prokaryotic and eukaryotic cells using a code in which the ‘letters’ are the four bases of DNA.
