A normal peptide has 100 amino acids.
Following mutation, it has only 20; 1–10 are the
same as the normal peptide; 11–20 differ from
the normal peptide. Which of the following
mutations occurred?
(A) Nucleotide deletion in the codon for
amino acid 11 (codon 11)
(B) Nucleotide deletion in codon 20
© Nucleotide deletion in the intervening
sequence
(D) Nucleotide substitution in codon 11
(E) Nucleotide substitution in codon 20
