DNA: an Overview

DNA, or deoxyribonucleic acid, is contained inside all living things. DNA contains the necessary instructions for protein synthesis and replication. Protein synthesis is the production of protein, which is used by cells or viruses for development. Replication is the process by which DNA copies itself for each replication or virus, passing on the information needed for the protein synthesis. The nucleuses of cells contain DNA, which is stored on chromosomes.
A molecule of DNA is in the shape of a double helix, or two spiral staircases wrapped around each other. …
