In this article we will discuss about the Mechanism of Protein Synthesis in Prokaryotes and Eukaryotes. Protein synthesis in the cell is conducted by ribosomes that are found attached to the membrane of endoplasmic reticulum and microsomes, as well as in free state in the groundplasm. The main components that take part in protein synthesis at cellular level are: 20 [...]
The following points highlight the three main steps involved in mechanism of protein synthesis. The steps are: 1. Initiation of Protein Synthesis 2. Elongation of Polypeptide 3. Termination of Protein Synthesis. Mechanism of Protein Synthesis: Step # 1. Initiation of Protein Synthesis: (i) Amino Acid Activation: The amino acid (AA) is activated by the enzyme "aminoacylsynthetase", and energy is provided [...]
The following points highlight the eighteen steps involved in the protein synthesis in plants. (i) DNA in the nucleus or nucleoid in prokaryotes directs the synthesis of m-RNA and provides it with necessary genetic information in the form of codons for the formation of specific proteins. This process is called as transcription. m-RNA is synthesized in the presence of the [...]
