Vedclass · Answer

(A) Gene cloning is a molecular biology technique used to produce multiple identical copies of a specific gene or $DNA$ fragment.$1$. The process begins by isolating the gene of interest and ligating it into a suitable vector (such as a plasmid).$2$. This creates a recombinant $DNA$ molecule.$3$. The recombinant $DNA$ is then introduced into a host cell (usually a bacterium) through a process called transformation.$4$. As the host cell divides,the recombinant $DNA$ is replicated along with the host's genome.$5$. Eventually,a bacterial colony is formed where each cell contains multiple copies of the cloned gene.
