Question

What should be the nature of the genetic code if there would have been 65 amino acids?

Answer 1

The sequence of DNA and RNA that codes for the amino acid sequence of protein during translation are called genetic code. The cell generates protein by mRNA translation. Inside the cell three base pairs of mRNA are read at a time, which code for a single protein.

Complete answer:
The nature of genetic code doesn’t change if there would have been 65 amino acids. The nature of the genetic code is not dependent on the number of amino acids. The codons are triplet in nature.
Genetic codes are degenerate, which means that some amino acids are coded by more than one codon.
Genetic codes are unambiguous, that is one codon code for one amino acid and hence it is also called specific.
These genetic codes are nearly universal in nature, a single codon codes for a single amino acid in all living organisms whether unicellular or multicellular.
These codons are read in a contagious fashion. No punctuation is used while writing or reading a codon.
The codon AUG has a dual function, it acts as a start or initiator codon and also codes for Methionine amino acid.
The coding UAA, UGA, and UAG does not code for any amino acid and functions as a stop codon.

Note:
George Gamow was a physicist who stated the fact that codons are triplet in nature.
Translation is the process of polymerization of amino acid to form a polypeptide chain.
Ribosome is the Cellular factory responsible for synthesizing protein inside cells. The process of translation occurs in the cytosol region of a cell.
