Molecular Basis Of Inheritance Question 2

Question: Match List I with List II.

Sure, here is the information you provided in a markdown table format:

List I List II
A. Gene ‘a’ I. B-galactosidase
B. Gene ‘y’ II. Transacetylase
C. Gene ‘i’ III. Permease
D. Gene ‘z’ IV. Repressor protein

Choose the correct answer from the options given below:

(1) A-III, B-I, C-IV, D-II

(2) A-II, B-I, C-IV, D-III

(3) A-II, B-III, C-IV, D-I

(4) A-III, B-IV, C-I, D-II

Show Answer

Answer: (3) A-II, B-III, C-IV, D-I

Explanation-

Lac operon- The genes in the operon encode proteins that allow the bacteria to use lactose as an energy source.

  • Gene ‘a’ is responsible for producing Permease.
  • Gene ‘y’ is responsible for producing Transacetylase.
  • Gene ‘i’ is responsible for producing the Repressor protein.
  • Gene ‘z’ is responsible for producing B-galactosidase.
