The following points highlight the six main stages involved in protein synthesis of prokaryotic and eukaryotic systems. The stages are: 1. Amino Acid Activation and Formation of Amino Acyl-t-RNA 2. Binding of m-RNA to the Ribosome 3. Formation of Initiation Complex 4. Polypeptide Chain Elongation 5. Polysomes 6. Co Transcriptional Translation. Stage # 1. Amino Acid Activation and Formation of [...]

In this article we will discuss about:- 1. Meaning of Proteins 2. Properties of Proteins 3. Reaction 4. Types. Meaning of Proteins: Proteins are large-sized heteropolymeric macromolecules having one or more polypeptides (chains of amino acids). The term polypeptide is often used interchangeably with protein. However, a single polypeptide must be at least 50 amino acid long in order to [...]
