154. Match the following genes of the Lac operon with their respective products:

(A) igene

(i) $\beta$-galactosidase

(ii) Permease

(iii) Repressor

(iv) Transacetylase

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

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

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

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

Show Answer

Answer : c

Hints & Solution

(c) Lac operon consist of one regulatory genes ( $i$ gene) and three structural genes $(z, y$, and $a$ ).

  • $i$ gene codes for Repressor.
  • $z$ gene codes for Beta-galactosidase.
  • $y$ gene codes for Permease.
  • $\quad a$ gene codes for Transacetylase.
