Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans?

• The bacteria have been grown on a petri dish containing insulin.

• The bacteria have been genetically engineered to contain the DNA needed to produce insulin.

• The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.

• The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.
