Activation of an amino acid during protein synthesis requires a participiation of specific molecule of :

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

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

Assertion (A): Aminoacylation is an essential step for the synthesis of protein. Reason (R): It is the process of adding an activated amino acid to the acceptor arm of a transfer RNA.

Consider the following statements (A). r-RNA provides the template for synthesis of proteins (B) tRNA brings amino acids and reads the genetic code (c ) RNA polymerase binds to promother and initiates transcription (D) A segment of DNA coding for polypeptide is called intron

Arrange the following steps in correct order: (TRANSCRIPTION): (I) The nascent RNA separates and RNA polymerase also detaches and thus terminates the process of transcription. (II)RNA polymerase loses the factor, but continues to add ribonucleotides to form RNA. (III) Binding of RNA polymerase to the promoter and its association with initiation factor (sigma) . (IV) The RNA polymerase associates with termination-factor (rho) transiently to stop the transcription process.
