Protein synthesis is the manner in which cells build proteins. The term is occasionally used to refer only to protein translation but generally it refers to a multi-step process, beginning with amino acid synthesis and transcription which are then used for translation. Since the beginning of evolution, cells have developed the capacity to synthesize proteins. They can generate new proteins either for reproduction or to simply replace a degraded one. Protein synthesis begins in the cell’s nucleus when the gene encoding a protein is copied into RNA. Genes, in the form of DNA, are embedded in in the cell’s chromosomes. The stage of submitting the gene’s DNA into RNA is called transcription. Translation produce in four phases: activation, initiation, elongation and termination. Translation occurs in the cytoplasm where the ribosomes are located.

Protein synthesis, even though very same, differs between prokaryotes and eukaryotes. Protein synthesis is not a easy process. Translation is necessarily preceded by transcription. Proteins shakes are widely used in cells to serve diverse functions. Some proteins afford the structural support for cells while others act as enzymes to catalyze certain reactions. Ribosomes are made of a small and large subunit which surrounds the messenger RNA. Although the outcome of protein synthesis can be involved and quite complex, its objective is rather straightforward. The purpose of protein synthesis is commonly to create a polypeptide — a protein made out of a chain of amino acids. During protein synthesis, the separate amino acids are reassembled into new chains. Each kind of protein powder has its own singular sequence of amino acids, which differs from the sequence in every other kind of protein.
