Only DNA polymerase has a proofreading ability. t-RNA refers to the transfer RNA molecule, which plays a very important role in translation. Overview of Translation In Ribosome The translation aids in the formation of proteins from the mRNA template and the nucleotide sequence at RNA is translated to the amino acid sequence of proteins in the ribosomes. Multiple Choice . Answer: During translation,ribosomal subunits assemble together like a sandwhich on the strand of mrna where they proceed to attract trna molecules tethered to amino acids a long chain of amino acids emerges as ribosome decodes the mrna sequence into polypepide or a new protein. During translation, the messenger RNA decodes the ribosome and produces an amino acid chain or polypeptide. Why? The positron of the 3' end of the RNA would be unstable, inhibiting elongation.
