Biotech Review

How has biotechnology helped to improve the agricultural industry?

• by developing irrigation systems that cover a large land area

• by creating some crops that resist certain insects

• by producing soil free of decomposers

• by developing machines that help farmers harvest crops faster

Scientists have been able to cause some bacteria to produce insulin. In which area of science would these scientists most likely work?

• biotechnology

• nuclear engineering

• marine biology

• chemistry

Restriction enzymes are analogous to what common school supply?

• glue

• scissors

• paper

• highlighter

What is a plasmid?

• a section of the human genome

• a material that cuts DNA
