For each mutant sequences below, give the type of mutation that occurred to produce the mutant sequence. (Note: the “…” indicates unspecified amino acids and types of mutations you might want to consider are insertions, deletions, missense, nonsense, and silent).

Normal: Met-Gly-Glu-Thr-Lys-Val-Val- ... -Pro

Mutant 1: Met-Gly

Mutant 2: Met-Gly-Glu-Asp

Mutant 3: Met-Gly-Arg-Leu-Lys

Mutant 4: Met-Arg-Glu-Thr-Lys -Val-Val - ... -Pro

The effect of base-pair substitution mutations on protein function varies widely from no detectable effect to the complete loss of protein function (null allele).

Part A Why do the functional consequences of base-pair substitution vary so widely? Select the four correct answers.

1. Nucleotide substitutions might not cause changes in the amino acid sequence of the protein.

2. The reading frame of the gene could be affected by base-pair substitution mutations, which almost always leads to lack of function.

3. Nucleotide substitutions in exons always lead to changes of amino acids in the protein.

4. The reading frame of the gene could be affected by base-pair substitution mutations, which rarely leads to lack of function.

5. Missense mutations create amino acid substitutions, which might affect protein functionality.

6. Mutations that occur in the intron sequences generally do not affect protein functionality.
