Protein Synthesis

Protein Synthesis is the process whereby DNA (deoxyribonucleic acid) codes for the production of essential proteins, such as enzymes and hormones. Proteins are long chains of molecules called amino acids. Different proteins are made by using different sequences and varying numbers of amino acids. The smallest protein consists of fifty amino acids and the largest is about three thousand amino acids long. Protein synthesis occurs on ribosomes in the cytoplasm of a cell but is …showed first 75 words of 863 total…

Before the synthesis of a protein begins, amino acids are attached to the tRNA molecule, which transport and attach them to the mRNA with the aid of rRNA, this is known as translation. Peptide bonds then form between the amino acids. Once the chain is completed the polypeptide chain separates from the tRNA and move in to the cytoplasm and in this way a protein is formed.
