Unit 5: Biotechnology

What is a GMO?

(LT 1)

• an altered organism that can live longer than unaltered organisms

• any organism that has acquired one or more genes by artificial mean

• only plants that have new cells implanted inside of their stem

• cells are changed within an organism- plant cells are switched with bacteria cells

All of the following are pros of GMOs except...

(LT 2)

• Longer shelf life of food

• illnesses can be cured

• food can taste better

• unnatural

When recombinant DNA is formed, it is implanted into a ______ cell in order to _______.

(LT 3)

• bacteria, replicate

• plant, increase in size

• animal, decrease in size

Recombinant DNA is...

(LT 4)

• when DNA is broken apart to form 2 or more DNA strands

• when one or more DNA strands are bonded together from different organisms

• when DNA is recombined without base pairing rules

• when DNA is replicated and sent to other cells

A plasmid is located in a _____ cell.

(LT 4)

• plant

• animal

• bacteria

How do scientists "cut and paste" DNA?

(LT 5)

• with enzymes

• with amino acids

• with carbohydrates

• with lipids

Restriction enzymes know where to cut DNA bases on their own specific _________.

• Recognition Site

• Recombinant DNA

• Restriction Pattern

• mRNA sequence

proteins that recognize and bind to specific DNA sequences and cut the DNA at or near the recognition site.

(LT 6)

• Restriction Enzyme

• Plasmid

• Recombinant DNA

• Genetically Modified Organism

The restriction enzyme cuts both sides of a DNA molecule so that there is a “tail” left on each strand.

(LT 7)

• Sticky End

• Blunt End

When a restriction enzyme cuts DNA directly across from one another.

(LT 7)

• Sticky End

• Blunt End
