To produce transgenic bacteria that make insulin, which of the steps listed below would a scientist do FIRST? A Insert the human insulin gene into a plasmid.
B. Extract the insulin from the bacterial culture
C. Cut out the insulin gene from human DNA.
D. Transform bacteria with the recombinant plasmid.

Transgenic organism is an organism, which received one or more genes from another organism. In transgenic bacteria, in order to insert the insulin, the scientist will first slice the gene from human DNA.

The correct option is:

Option C. Cut out the insulin gene from human DNA.

Transgenic bacteria are produced by recombinant DNA technology. Scientists have made it possible to manipulate the genetic sequence of an organism, such that human genes can be inserted into the genetic material of a bacterium.

The scientists will primarily cut out the insulin gene from the human DNA with the help of restriction enzymes. The cutout part of the insulin gene will be incorporated into the bacteria with the help of vectors.

Thus, the correct option is C.

C. Cut out the insulin gene from human DNA.

this is done with an enzyme called lygase
