8.1 INTRODUCTION OF NUCLEIC ACIDS

A nucleic acid is a macromolecule composed of chains of monomeric nucleotides. In our body these molecules carry genetic information or form structures within cells. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids ...
