question 66

Multiple Choice

A mutation occurs in the promoter of a protein-encoding gene.How might this mutation affect the production of the protein encoded by the gene?

• A) The mRNA made from this gene would exhibit the same mutation and therefore would not fold or function properly.
• B) The protein made from the promoter would have a different amino acid sequence and therefore would not function properly.
• C) The promoter might not be recognized by RNA polymerase, so the enzyme would be unable to attach to the promoter and start transcription.
