Many people with diabetes require insulin to stay alive. Which best explains why the gene for human insulin is transferred into a bacterium for mass production?

Question

a
The bacterium will quickly repair the insulin gene, which allows it to be reinserted into a human.
b
The bacterium will quickly destroy the insulin gene and create a replacement, which is free of mutations.
c
The bacterium will produce insulin at a fast rate as an antibody response in reaction to the foreign gene.
d
The bacterium will produce insulin at a fast rate by incorporating the gene into its own genetic code.

Answer 1

d
The bacterium will produce insulin at a fast rate by incorporating the gene into its own genetic code.
