Study the image. Why have viruses been used in gene therapy?

• They pass easily from one person to another

• They are disease and cause disease symptoms

• They contain restriction endonucleases. (google that word)

• They inject DNA into cells. (Look at the picture again!!)

One problem with selective breeding is

• creating a new species

• gene variety is lost

• new food sources

Which is another term for selective breeding?

• Artificial selection
• Natural Selection
• Intelligent selection

Selective breeding is...

• a process to create an organism with desired traits from parents with those desired traits

• natural method of producing offspring with desired traits

• creating a new species

• making organisms reproduce during times of stress

Which outcome is possible using genetic engineering, but NOT using selective breeding?

• A bacterium that produces human insulin

• A sheep with wool longer than wool produced by any other sheep.

• A hairless variety of cow. (I'm sure that's cute)

• Corn that produces one large corn cob per plant.

A genetically engineered organism that contains a gene from ANOTHER organism is called a

• genetic organism

• cloned organism

• transgenic organism

• bacterial organism

The process of interbreeding individuals from genetically distinct populations to produce a hybrid.

• hybridization

• cloning

• inbreeding

• genetic engineering

A restriction enzyme cuts a segment of DNA into 8 pieces.  How many restriction sites are there?

• 6
• 7
• 8
• 9

Why are primers necessary for PCR?

• They help separate the double helix
• They are a starting point for DNA polymerase
• They help anneal the newly formed strands
• They bring in new nucleotides

An organism that contains DNA from another organism is called:

• transatlantic
• recombinant
• binary
• selective species
