Question

Match the following genes of the Lac operon will their respective products:

Column - 1		Column - II
(a)	i gene	(i)	β-galactosidase
(b)	z gene	(ii)	Permease
(c)	a gene	(iii)	Repressor
(d)	y gene	(iv)	Transacetylase

Select the correct option:

• A. $a \rightarrow iii, b \rightarrow i, c \rightarrow iv, d \rightarrow ii$
• B. $a \rightarrow iii, b \rightarrow iv, c \rightarrow i, d \rightarrow ii$
• C. $a \rightarrow i, b \rightarrow iii, c \rightarrow ii, d \rightarrow iv$
• D. $a \rightarrow iii, b \rightarrow i, c \rightarrow ii, d \rightarrow iv$

Answer 1

Answer: (A)

In lac operon
i gene $\to$ Repressor
z gene $\to$ $\beta$-galactosidase
y gene $\to$ Permease
a gene $\to$ Transacetylase
