In the laboratory, scientists remove the gene for insulin from human chromosomes. They insert the gene into the DNA of bacterial cells. This causes the bacterial cells to produce human insulin, which is used to treat diabetes in humans. Which of the following best explains why bacteria is able to use human DNA? A. The DNA code is the same in bacteria and humans. B. The proteins used to make insulin are the same in humans and bacteria. C. The mRNA produced by the insulin matches the mRNA produced by bacteria. D. The insulin produced by bacteria is different from the insulin produced by humans.

Insulin is a complex protein molecule produced by the pancreas in all vertebrates. It is a hormone that regulates carbohydrate metabolism. Inability to produce insulin results in diabetes mellitus. Diabetes is treated by injections of insulin. Given the law of definite proportion, would you expect there to be any differences in chemical activity between human insulin extracted from pancreatic tissue and human insulin produced by genetically engineered bacteria? Why or why not?
The Human Genome Project showed that human DNA is not considerably bigger than much simpler organisms, with about 30,000 total genes. However, humans make over 100,000 different proteins. How is this possible? (Hint: Think about splicing.)
