Question

why we not put a gene directly to the host....why we required a plasmid vector to take it to the host​

Answer 1

We cannot put a gene directly into the host because it won't be integrated in it like this.

Explanation:

• We cannot put a gene directly into the host because the gene needs to be integrated into the genome of the host.

• The genome of an organism is enclosed in the nucleus and a gene directly cannot reach there.

• Hence, a gene can be inserted into a host chromosome genome through plasmids. As the plasmid will replicate, the gene will also be replicated.
