Match the columns.
Column-$I$ Column-$II$ $(a)$ Splicing $(1)$ Lac Operon $(b)$ Okazaki fragments $(2)$ Lagging strands $(c)$ Jacob and Monod $(3)$ Lactose $(d)$ Inducer $(4)$ Removal of introns
| Column-$I$ | Column-$II$ |
| $(a)$ Splicing | $(1)$ Lac Operon |
| $(b)$ Okazaki fragments | $(2)$ Lagging strands |
| $(c)$ Jacob and Monod | $(3)$ Lactose |
| $(d)$ Inducer | $(4)$ Removal of introns |
$(A)$ The correct matches are as follows:
$(a)$ Splicing refers to the process of removing introns and joining exons in pre-mRNA, which corresponds to $(4)$.
$(b)$ Okazaki fragments are short $DNA$ sequences synthesized discontinuously on the lagging strand during $DNA$ replication, which corresponds to $(2)$.
$(c)$ Jacob and Monod were the scientists who proposed the operon model, specifically the Lac Operon, which corresponds to $(1)$.
$(d)$ An inducer is a molecule that regulates gene expression by binding to a repressor protein; in the Lac Operon, lactose acts as the inducer, which corresponds to $(3)$.
Therefore, the correct matching is $(a-4, b-2, c-1, d-3)$.
