Text Solution

Verified by Experts
The correct answer is:
A

The process of making recombinant DNA molecule involves the introduction of a desired gene into the DNA of a host that will produce the desired protein.
Inducing a cloned eukaryotic gene to function in a prokaryotic host can be difficult sometime. The presence of long non-coding introns in eukaryotic genes may prevent correct expression of these genes in prokaryotes, which lack RNA-splicing machinery.
