Mention the two steps in activation of amino acid translation.

Activation of amino acids during translation is done by

What is meant by activation of amino acids?

Transcription I. IS the coping of a complementary mRNA on a DNA strand II. Requires a template, activated precursors, a divalent metal ion and RNA polymerase III. Is the first step in activation of amino acid IV. Directs the order of specific amino acids to form a polypeptide or protein

During translation, the activation of amino acids I.Takes place through their carboxyl groups II.Continues until a termination codon reaches the ribosome III. Is catalysed by its own activating enzyme called aminoacyl tRNA synthetase IV. Involves movement of second amino acid tRNA complex from A-site to P-site

The main steps involved in the process of translation are I.Activation of amino acid II.Initiation of polypeptide chain synthesis III.Termination of polypeptide chain formation IV. Transfer of polypeptide chain to tRNA

Mention the steps involved in ionsiation of phosphoric acid

Transfer RNA is present in the cytoplasm and help in bringing activated amino acids to ribosomes.

Mention briefly the initiation phase of translation process.
