How is the human insulin gene introduced into bacteria?

Question

A. By using heat to change the bacteria's DNA.
B. By cutting and pasting it into a plasmid.
C. By injecting it directly into bacteria.
D. y exposing bacteria to insulin.

Answer 1

The correct answer is B. By cutting and pasting it into a plasmid.

In genetic engineering, the human insulin gene is introduced into bacteria (such as E. coli) by first isolating the gene and then incorporating it into a plasmid, which is a small, circular piece of DNA that can replicate independently within a bacterial cell. The plasmid acts as a vector to carry the human gene into the bacteria, allowing them to produce insulin.
