NUCLEIC ACIDS, DNA REPLICATION AND PROTEIN SYNTHESIS BY CHIKA OKOSI How does DNA direct a cell's activities? How does a cell in your liver "know" it's a liver cell and not a brain cell or kidney cell. How can all this information needed to regulate the cell's activities be stuffed into a tiny nucleus? To begin to find the answer to all these questions, an in-depth in the biological molecules nucleic acids needs to be established. An organism has some form of nucleic acid that is the chemical carrier of its genetic information. There are two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that code for all the information that determines the nature of the organism's cells. In fact DNA codes for all the instructions needed for the cell to perform different functions. Nucleic acids are one of the several macromolecules in the body in addition to facts, proteins and...
