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

After the addition of the last amino acid to a growing polypeptide chain during the process of protein synthesis, one of the termination codons reaches the appropriate site on the ribosomal surface and then the following envents take place (i) Release of t-RNA molecule from the ribosome. (ii) Dislodging of polypeptide chain from the t-RNA (iii) Dissociation of ribosomes into large and small subunits. ltBrgt The correct sequence of these events:

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

The translation process involves the following steps: (I) Binding of ribosome and mRNA at the start codon (AUG). (II) Recognition of start codon (AUG) by initiator tRNA. (III) Amino acids are activated in the presence of ATP (IV) Amino acids bind with the enzyme aminoacyl tRNA synthetase Choose the correct sequence:

The following features occur during protein synthesis: (a) Movement of mRNA from the nucleus into the cytoplasm, where it binds to the ribosomes (b) Formation of tRNA-amino acid complex (c) Transcription of specific segments of DNA into mRNA molecules in the nucleus (d) Binding of N-terminal amino acid, methionine tRNA to the 'P' site of the ribosome. The tRNA anticodon 'pairs with AUG on mRNA' (e) Formation of peptide bond between first and second amino acids at the A site (f) Release of the complete polypeptide chain from mRNA and the ribosomes (g) Migration of dipeptide to form a tripeptide and then a polypeptide The correct order of events is:
