Draw a positive repressible with a high concentration

Reference no: EM13153508

For this question, use a square for the RNA polymerase, a circle for the anpoinducer/repressor; an eclipse for the ribosome, and an X for the trigger. Unless specified otherwise, the drawing should reflect the time at which initiation of the transcription should occur. Include the cap region, operator region, and three cistrons.

a) Draw a positive repressible with a high concentration of the trigger

b) draw a positive repressible with a low concentration of the trigger

c) Draw a histidine leader sequence at the time of attenuation

d) draw the Lac operon with a high concentration of lactose and when there is no glucuse in the cell. Include all types of regulation

e) There are two possible ways for the trp operon to be turned off (one of which is attenuation). Make two drawings, first show how it would be turned off BEFORE trnascribing the leader region.

In the second, show how it would look when it is attenuated.
