question 43

Multiple Choice

How might a single base substitution in the sequence of a gene affect the amino acid sequence of a protein encoded by the gene,and why?

• A)A single amino acid could change, but the reading frame is unaffected.
• B)The amino acid sequence would be substantially altered, because the reading frame would change.
• C)All amino acids following the substitution would be affected, because the reading frame would be shifted.
• D)It is not possible for a single base substitution to affect protein structure, because each codon is three bases long.
• E)There would be no impact, as two or three base pairs must change to result in a change at the amino acid level.
