Question

Manufacturing recombinant dna molecules involves cutting a gene from its normal location, inserting it into a circular piece of dna from a bacterial cell, and then transferring the circle of dna to cells of another species. which of the below describe the circular piece of dna?

Answer 1

Answer: Plasmid.
A plasmid is a small DNA molecule within a bacteria cell that is separated from the chromosomal DNA and can replicate independently. Through Recombinant DNA, we can insert a gene that we want to see replicated in the plasmid, and when the bacteria multiplies, which it does often, we will obtain a lot of copies of interest gene.
