A hypothetical mRNA, AUG CGC CUA AAG AGG codes for five amino acids. What will happen if you delete the first C? Will five amino acids still be coded for? Give reasons.

Solution
The genetic code is defined as the structure of nitrogenous bases in RNA molecule which contains the information for the synthesis of the protein molecule.
One of the features of the genetic codon is that a single amino acid is specified by the sequence of three nucleotides and mRNA.
There is no pause and the genetic codon is read commaless.
If there is a deletion of a genetic codon then the entire sequence is changed
New sequence will be-
AUG GCC UAA AGA GG
At the start, the codon is unaffected and therefore the protein will be formed but all five amino acid will not be coded only 4 of them will be coded and they will be different from the original sequence of amino acids that were to be coded because of the deletion.
