Proteins synthesis
Proteins are made up of amino acids. Proteins are in the form of one or more chain called polypeptide chains. Within the polypeptide chains, the amino acids and amides are linked through peptide bonds, involving the carboxyl group of one amino acid and the amino group of the nex..
Mechanism of Protein Synthesis
The events in protein synthesis are better known in bacteria than in eukaryotes. Although these are thought to be similar in the two groups there are some differences. The following description refers mainly to protein synthesis in bacteria on the 70S ribosom..

Translation-Synthesis of Proteins
Translation is the mechanism by which the triplet base sequence of an mRNA guides the linking of a specific sequence of amino acids to form a polypeptide (protein) on ribosomes. All the proteins a cell needs are synthesized by the cell within itse..
Energy Used for Protein Synthesis
One GTP is hydrolysed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome. A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA. One ATP is hydrolysed to AMP during amino acid activation. Thus, the formation of each peptide bond..

Advantage of the Regulation of Gene Action
An operon is the unit of transcription. When excess protein is present, it is no longer economical for the cell to use up its energy and materials in the synthesis of enzymes that are not immediately needed. Hence, the protein synthesis is stopped. This..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
Good teaching skills, an amazing tutoring, would recommend it to everyone - Maadai
Very informational yet simple and easy to comprehend. Tutor Vista is helping me a lot.
Extremely helpful, would love to have more session. Tutor gave me a clear understanding of what I needed help with the most. Great session.
