During the 1950s and 1960s, it became credible that DNA is capital in the amalgam of proteins. Proteins are acclimated in enzymes and as structural abstracts in cells. Many specialized proteins action in cellular activities. For example, in humans, the hormone insulin and the beef corpuscle filaments are composed of protein. The hair, skin, and nails of bodies are composed of proteins, as are all the hundreds of bags of enzymes in the body.

The key to a protein atom is how the amino acids are linked. The arrangement of amino acids in a protein is a blazon of cipher that specifies the protein and distinguishes one protein from another. A abiogenetic cipher in the DNA determines this amino acerbic code. The abiogenetic cipher consists of the arrangement of nitrogenous bases in the DNA. How the nitrogenous abject cipher is translated to an amino acerbic arrangement in a protein is the base for protein synthesis.

For protein amalgam to occur, several capital abstracts charge be present, such as a accumulation of the 20 amino acids, which comprise best proteins. Addition capital aspect is a alternation of enzymes that will action in the process. DNA and addition anatomy of nucleic acerbic alleged ribonucleic acerbic (RNA) are essential.

RNA is the nucleic acerbic that carries instructions from the nuclear DNA into the cytoplasm, area protein is synthesized. RNA is agnate to DNA, with two exceptions. First, the carbohydrate in RNA is ribose rather than deoxyribose, and second, RNA nucleotides accommodate the pyrimidine uracil rather than thymine.
