Question
Chapter 12, Problem 2RE
Interpretation Introduction
Interpretation:
The reason for the fact that a two base genetic code encoding a single amino acid is not sufficient for the synthesis of proteins is to be explained.
Concept introduction:
Genetic code is a triplet of nucleotides utilized by the cells to interpret the information, which is coded in the genetic material, into the proteins.
The translation of this information is achieved by ribosomes, which bind the amino acids in a sequence specified by the messenger RNA (mRNA), utilizing the transfer RNA (tRNA) to bring the amino acid residues and to read mRNA the three nucleotides at an instant.
