    Match the following genes of the Lac operon with their respective products:
    [a] \[i\] gene (i) P-galactosidase
    [b] \[z\] gene (ii) Permease
    [c] \[a\] gene (iii) Represser
    [d] \[y\] gene (iv) Transacetylase
    Select the correct option.

    A)
    \[[a]\to (i)\] \[[b]\to (iii)\] \[[c]\to (ii)\] \[[d]\to (iv)\]

    B)
    \[[a]\to (iii)\] \[[b]\to (i)\] \[[c]\to (ii)\] \[[d]\to (iv)\]

    C)
    \[[a]\to (iii)\] \[[b]\to (i)\] \[[c]\to (iv)\] \[[d]\to (ii)\]

    D)
    \[[a]\to (iii)\] \[[b]\to (iv)\] \[[c]\to (i)\] \[[d]\to (ii)\]

    Correct Answer: C

    Solution :

    In lac operon
    \[i\,gene-Represser\]
    \[z\text{ }gene-\beta -galactosidase\]
    \[y\text{ }genePermease\]
    \[a\text{ }geneTransacetylase\]
