Question:medium

Write the number of amino acids that would be in the polypeptide synthesised by a similar mRNA as above, where in the fourth codon instead of ‘C’ there is ‘U’. Justify your answer.

Show Hint

Premature stop codons caused by mutations can lead to truncated proteins and loss of function.
