What would you assume if you had RNA transcripts of lactose-utilizing genes within E. coli?

1) the presence of lactose


2) the absence of lac operon repressor protein


3) the presence of lac operon activator protein


4) the binding of lactose to the lac operon activator


5) the absence of amino acids





Which one is correct? Thanks TONS!!What would you assume if you had RNA transcripts of lactose-utilizing genes within E. coli?
Depending upon your level of study of course! option 2 would be the most straight-forward answer. i.e. absence of LO Repressor prot.


Lactose initiates its own breakdown by attaching to the Repressor protein thereby allowing the operator to be expressed (resulting in transcription of RNA sequences of the gene).
