The Trp Operon in E

question 40

Multiple Choice

The trp operon in E. coli contains a 5' UTR sequence that is translated into a small polypeptide of 14 amino acids, which includes two tryptophans. If the two trp codons in the 5' UTR of the RNA are changed to serine codons and the resulting cells are starved for tryptophan but not for any other amino acid, what will be the effect of the mutant codons on the operation of the trp operon?

• A) The trp repressor will be synthesized in greater amounts.
• B) Expression of the trp structural genes will be less than with a normal trp operon.
• C) Expression of the trp structural genes will be greater than with a normal trp operon.
• D) The leader polypeptide will not be synthesized.
• E) The expression of the operon will not be affected by these mutations.
