Chapter 12, Problem 2CQ
Summary Introduction
To explain: The function of aminoacyl tRNA synthetases.
Introduction: The tRNA or transfer RNA is a facilitator molecule which transports the amino acids to the ribosomal units where mRNA is translated into protein. This tRNA works like adaptor molecule and translocates various amino acids for the manufacture of the peptide chain of the protein.
