Question

Indicate the source of repressor protein and the operator region(s) to which it binds. Then indicate how this affects expression of lac genes from the F' plasmid and from the bacterial chromosome.

Answer 1

Role of F plasmid

Explanation:

• The F plasmid is a example of an large plasmid, which contains qualities that permit the plasmids DNA to be moved between cells
• It is found in the bacterium E. This joining by means of a pilus so as to move DNA between microorganisms is known as conjugation. Thusly the F plasmid is known as a conjugative plasmid.  
• The F-factor permits the giver to create a dainty, tube like structure called a pilus
• which the benefactor uses to contact the beneficiary
• The pilus at that point draws the two microorganisms together, at which time the contributor bacterium moves hereditary material to the beneficiary bacterium
