Question
The trp operon includes five genes needed for typtonphan synthesis in E. coli - trpE, trpD, trpC, trpB and trpA (listed in order on the operon). If a nonsense mutation occurred at the beginning of trpC: how long would the transcript of the operon be? Choose one answer, And how many proteins would be translated? A. The transcript would stop after trpC and only trpE, trpD and part of trpC would be translated B. The transcript would stop at trpC and only trpE and trpD proteins would fold correctly C. The transcript would stop after trpA and only trpE and trpD proteins would be functional D. The transcript would stop at trpE and none of the proteins would be translated|Explanation / Answer
Answer:
The trp operon includes five genes needed for tryptophan synthesis is E.coli – trpE , trp D, trp C, trp B and trp A (listed In the order on the operon). If a nonsense mutation occurred at the beginning of trpC: how long would the transcript of the operon be?
