Ans) In the absence of tryptophan, the genes in the operon should be transcribed. So, option B is correct.
Explanation:
Tryptophan operon is negatively repressible operon because it is inhibited in the presence of effector molecule(repressor) which is tryptophan.
Tryptophan act as a co-repressor of the operon as it binds to the aporepressor and thus activates the aporepressor which in turn shuts off the transcription of the operon genes.
So, in the absence of tryptophan, aporepressor would not get activated, resulting in transcription of the operon genes.

In this problem you will explore how to solve problems involving partial diploid lac operon bacterial strains. Bacterial strains that are "partially diploid" have two copies of the lac operon because they aquired a plasmid carrying just the lac operon region. One copy of the lac operon region is on the recipient's bacterial chromosome, and the other copy is on the F' plasmid that was introduced into the cell by conjugation. Partial diploid genotypes are written with the F' segment...
