an Auxotrophic E

question 69

Multiple Choice

Use the following to answer questions
An auxotrophic E. coli strain requires adenine to grow because of a mutation in a gene for an adenine synthesis enzyme. The following shows part of the wild-type and mutant alleles of the gene, including the start codon. The bottom strand is the template for transcription. $$\begin{array} { c c } \text { ade } 1 ^ { + } \text {wild-type allele } & \text { ade1 } ^ { - } \text {mutant allele } \\\text { 5'...TTATGGGCAAGATCCCA...3' } & \text { 5'....TTA TGGGCTAGATCCCA...3' } \\\text { 3'...AATACCCGTTCTAGGGT...5' } & \text { 3'...AATATGGGCTAGATCCCA...3' }\end{array}$$
-How does the mutation affect the enzyme?

• A) The protein won't be synthesized and translation will stop at the third codon.
• B) The protein will not be changed because the mutation did not change the amino acid.
• C) The protein will be changed because the mutation altered the amino acid.
• D) The protein will not be changed because the mRNA was not changed.
