An alternative to genetic engineering is carefully choosing the parent organisms and breeding them to arrive at desired traits in the offspring. This is called:

• Genetic engineering

• Bacterial Transformation

• Cloning

• Selective breeding

Organisms that have had DNA from other organisms inserted into their DNA to produce certain traits are called:

• Plasmids

• Clones

• Transgenic organisms

• Recombinant organisms

Which of the following is a medical application of genetic engineering?

• Inserting human DNA into bacterial DNA for insulin production

• Manipulating of DNA to produce glowing monkeys

• Engineering crops for greater nutritional content

• Modifying genes to achieve a desirable phenotype
