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

Answer 1

The correct answer is:

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

This is because when the human insulin gene is transferred into a bacterium (often E. coli), the bacterium's machinery can be used to express the gene and produce insulin efficiently. By incorporating the gene into its own genetic code, the bacterium can replicate and produce large quantities of insulin, which is essential for medical use, especially for those with diabetes.
