Question

For each of the following types of transcriptional control, indicate whether the protein produced by the regulator gene will be synthesized initially as an active repressor, inactive repressor, active activator, or inactive activator.a. Negative control in a repressible operonb.b. Positive control in a repressible operonc.c. Negative control in an inducible operond.d. Positive control in an inducible operon

Answer 1

The type of protein synthesized for each case of transcriptional control is given below:

a. Negative control in a repressible operon

Inactive repressor

b. Positive control in a repressible operon

Active activator

c. Negative control in an inducible operon

Active repressor

d. Positive control in an inducible operon

Inactive activator

Step-by-step explanation:

Different types of operons exist in different bacterial systems and they control the transcription of genes by means of regulator proteins. These proteins are responsible for turning on or off the gene encoding a particuar protein depending on whether or not the cell requires for it.
