Biotechnology Review

What do we call the enzymes that cut up DNA at specific sequences?

• Palindromes

• Restriction Enzymes

• DNA ligase

• Polymerases

What does PCR do?

• Amplifies DNA

• Separates DNA fragments according to size

• Cuts DNA

• Dissolves DNA

Which project is most likely to interest a scientist working at a biotechnology company?

• Study and reconstruction of fossilized bones.
• Conservation of key species within ecosystems.
• Development of genetically modified corn plants
• Prevention of sewage leaking into water supplies

Strawberries have been genetically modified to resist frost. How does this benefit farmers?

• A longer growing season.
• A pest-resistant berry.
• A larger berry.
• Easier harvesting.

How are scientists able to produce a type of corn that will repel insects?

• by not spraying the corn plants
• by soaking corn seeds in insect spray
• by changing the genetics of the corn plants
• by altering the temperature of soil so the insects will die

The process of changing the genetic material of a living organism 

• Genetic Modification
