The table shows tools used in genetic engineering. What is the role of the plasmid?
Answer Details
In the table the enzymes cut and join the gene, which leaves the plasmid to do the transport job. The plasmid acts as a vector that carries the gene into the bacterium: it is a small loop of DNA that takes up the gene and is then absorbed by the bacterial cell. Cutting DNA is the restriction enzyme's role, not the plasmid's, and a plasmid neither kills its host nor makes insulin by itself, since the gene it carries is what codes for the protein.
