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
- AA-III, B-I, C-IV, D-II
- BA-II, B-I, C-IV, D-III
- CA-II, B-III, C-IV, D-I
- 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- enzyme.
