Match the following genes of the lac operon with their respective products:

A

(iii) (iv) (i) (ii)

B

(i) (iii) (ii) (iv)

C

(iii) (i) (ii) (iv)

D

(iii) (i) (iv) (ii)

Step-by-Step Solution

According to the text describing the lac operon:

  • The i gene codes for the repressor of the lac operon.
  • The z gene codes for beta-galactosidase (-gal).
  • The y gene codes for permease, which increases permeability of the cell to -galactosides.
  • The a gene encodes a transacetylase.

Matching these typically corresponds to: (a) i gene (iii) Repressor; (b) z gene (i) Beta-galactosidase; (c) a gene (iv) Transacetylase; (d) y gene (ii) Permease (or similar variations depending on column arrangement, but Option 4 represents the correct biological pairing).
