Under what conditions is lac repressor bound to the lac operon?
See AnswerQ: How are the actions of lac repressor and trp repressor similar and
How are the actions of lac repressor and trp repressor similar and how are they different with regard to their binding to operator sites, their effects on transcription, and the influences of small ef...
See AnswerQ: Mutations may have an effect on the expression of the lac operon
Mutations may have an effect on the expression of the lac operon and the trp operon. Would the following mutations have a cis- or transeffect on the expression of the protein-encoding genes in the ope...
See AnswerQ: Would a mutation that inactivated lac repressor and prevented it from binding
Would a mutation that inactivated lac repressor and prevented it from binding to the lac operator site result in the constitutive expression of the lac operon under all conditions? Explain. What is th...
See AnswerQ: Chapter 21 describes a blotting method known as Northern blotting, which
Chapter 21 describes a blotting method known as Northern blotting, which can be used to detect RNA transcribed from a particular gene or a particular operon. In this method, a specific RNA is detected...
See AnswerQ: Looking at Figure 14.10, discuss possible “molecular ways
Looking at Figure 14.10, discuss possible “molecular ways†that the cAMP-CAP complex and lac repressor may influence RNA polymerase function. In other words, try to...
