Question
Select the two statement out of the foue (1-4) given below aboutlac operon.
(1) Glucose or galactose may bind with the repressor and inacivate it
(2) In the absence of lactose, the repressor bibd with the operator region
(3) The z- gene codes for permease
(4) this was elucidated by Francois Jacob and Jacques Monod.
The correct statement are
(1) Glucose or galactose may bind with the repressor and inacivate it
(2) In the absence of lactose, the repressor bibd with the operator region
(3) The z- gene codes for permease
(4) this was elucidated by Francois Jacob and Jacques Monod.
The correct statement are
Options
A.(2) and (3)
B.(1) and (3)
C.(2) and (4)
D.(1) and (2)
Solution
In prokaryotes, a hypothesis was given in 1961 to explain the protein synthesis regulation. this hypothesis was given by F Jacob and J Monod and for this awarded Nobel Prize in 1965, the hypothesis was known by the name of Operon Model.
The operator gene is the segment of DNA, which exercise a control over transscriptions. In the absence of lactose , the repressor bind with the oerator gene.
