Match List I with List II: List I List II A. Gene 'a' I. Beta-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:

Options

  1. AA-III, B-I, C-IV, D-II
  2. BA-II, B-I, C-IV, D-III
  3. CA-II, B-III, C-IV, D-I
  4. DA-III, B-IV, C-I, D-II

Correct answer

C. A-II, B-III, C-IV, D-I

Step-by-step solution

Gene 'a' The structural gene of the lac-operon which codes for Transacetylase enzyme . Gene 'y' The structural gene of the lac-operon which codes for Permease enzyme . Gene 'i' The i gene codes for the repressor of the lac operon. The repressor binds to the operator region to stop the transcription of structural genes. Gene 'z' The structural gene of the lac-operon which codes for b- β - Galactosides enzyme .
