Scientists have inserted the gene for human insulin into bacteria. These bacteria make the insulin protein, which can then be used by people who have diabetes. This process is an example of

-hybridization
-gene therapy
-selective breeding
-genetic engineering

my answer is D

Your answer is correct! The process described is an example of genetic engineering. Genetic engineering involves manipulating or modifying the DNA of an organism to achieve a desired trait or characteristic. In this case, scientists have inserted the gene for human insulin into bacteria, causing the bacteria to produce insulin. This genetically modified bacteria can then be used as a source for producing insulin to be used by individuals with diabetes.
