Biotechnology

An organism's collection of genes is...

• clone
• genome
• recombinant DNA
• DNA fingerprint

DNA fragments cut by a restriction enzyme, such as the EcoRI enzyme... 

• pair up and join with any other DNA fragments cut by the same restriction enzyme
• pair only with DNA from the same species.
• combine with any other spliced chromosome.
• pair only with fragments formed by a complementary restriction enzyme

Which segment will be cut by EcoRI?

• A
• B
• C
• D

As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow in the dark. These bunnies would be considered...

• transgenic organisms
• plasmids
• DNA fingerprints
• clones

A bacterial cell takes in foreign DNA from outside of the cell in a process called...

• DNA fingerprinting
• gene therapy
• GMO's 
• transformation

Transferring normal human genes into human cells that lack them...

• is called gene therapy
• will cause mutations
• is impossible at this time
• will cause antibodies to kill cells

A DNA molecule containing regions from different sources is called

• restriction enzyme
• recombinant DNA
• DNA fingerprinting
• clone

What can you infer about the bands in section D of the image?

• they are larger because they can travel faster
• they are smaller because they can travel faster
• they are the same size
• there is no way to know which one is smaller or larger

why are the bands in B moving toward the positive end of the gel?

• The bands consist of DNA, which is negatively charged
• The bands consist of DNA, which is positively charged
• The bands consist of RNA, which is negatively charged
• The bands consist of DNA, which is neutral

• Sheep A
• Sheep B
• Sheep C
• Lamb
