Final answer:
Advances in DNA technology have directly impacted human health by enabling the production of insulin by bacteria and the use of DNA fingerprinting for identification purposes.
Step-by-step explanation:
An example of an advance in DNA technology that has directly affected human health is the production of insulin by bacteria. Previously, insulin for diabetic patients was extracted from the pancreas of animals, but with the advances in DNA technology, scientists have been able to modify bacteria to produce human insulin. This has greatly improved the availability and affordability of insulin for diabetic individuals.
Another example of an advance in DNA technology that has directly affected human health is DNA fingerprinting. This technique is used to identify individuals by analyzing their unique DNA patterns. It has proven to be valuable in forensic investigations, solving crimes, and establishing paternity.
Cloning sheep, as mentioned in option D, is also an example of an advance in DNA technology, but its direct impact on human health is less significant compared to the other examples.
