Question

how can an alien piece of DNA made to multiply in a host cell

Answer 1

In a chromosome there is a specific DNAsequence called the origin of replication, which is responsible for initiating replication. ... Thus, an alien DNA is linked with the origin of replication, so that, this alien piece of DNA can replicate and multiply itself in the host organism

Answer 2

In a chromosome there is a specific DNA sequence called the origin of replication, which is responsible for initiating replication. Therefore, for the multiplication of any alien piece of DNA in an organism it needs to be a part of a chromosome which has a specific sequence known as ‘origin of replication’. Thus, an alien DNA is linked with the origin of replication, so that, this alien piece of DNA can replicate and multiply itself in the host organism. This is known as Cloning or making multiple identical copies of any template DNA.
