The tRNA functions to decode the mRNA, which contains the codes for the amino acid for the production of the proteins. At various sites within the ribosomes, these tRNA are functional and takes part in the process of translation.
A. The tRNA coding sequence if the mRNA strand is GCU-AAU-GUC will be the following:
CGA-UUA-CAG
B. The above coding sequence codes for the Alanine-Asparagine-Valine.
