QUESTION 33

What is an insertion mutation?

       
A codon is inserted in an mRNA strand, which alters all subsequent codons.

       
A nucleotide is inserted in a gene sequence, which alters all subsequent codons.

       
A codon is inserted in a gene sequence, which alters all subsequent nucleotides.

       
An amino acid is inserted in a protein chain, which alters all subsequent amino acids.

       
An amino acid is inserted in a protein chain, which may alter protein function.
