If there are 99 bases in an mRNA that codes for a protein with 33 amino acids and the base at position 30 undergo nonsense mutation, then what will be the length of polypeptide formed?

Options:

Answer:
C
Solution:

99 bases long mRNA chain can specify 33 amino acid, if nonsense mutation occurs and 30 position than10thcodon becomes stop codon, as a results the new mRNA can code for a protein with only 9 amino acid as the10thcodon becomes stop codon.
