A gene responsible for insulin production can be moved from human DNA into bacterial DNA. The bacteria are then grown to make human insulin. What advantage does this type of human insulin have for patients compared with insulin taken from other animals?

  • AIt will allow patients to pass the insulin gene to any offspring.
  • BIt will cause patients’ pancreas glands to start producing insulin again.
  • CIt will be more readily available as it can be produced on a commercial scale.
  • DIt will result in the transfer of the insulin gene to patients.
