What would you assume if you found RNA transcripts of lactose-utilizing genes within E.coli?
A) the binding of lactose to the lac operon activator
B) the presence of lactose
C) the presence of lac operon activator protein
D) the absence of lac operon repressor protein

Question

Quizplus · Accepted Answer

The presence of RNA transcripts of lactose-utilizing genes within E.coli suggests the presence of lactose, which would induce the expression of lac operon genes. The other choices may also be necessary for lactose utilization, but the presence of lactose is the most direct cause of the transcription of lactose-utilizing genes.
