"transgenic" refers to an animal that:

• Has DNA from another organism spliced into its genome

• Has undergone DNA modification

• Has unique genes for its species

In which ways can genetic engineering can improve crops

• Make them pest or drought resistant

• Make them more nutritious

• Make them larger

• All answers are correct

A circular piece of DNA, found in bacteria, is called:

• A plasmid

• mRNA

• Ribosome

• Nucleotide

Humans with genetic diseases can have a gene inserted into their body using a virus. This is called:

• Gene therapy

• Cloning

• DNA fingerprinting
