What does the origin of replication (Ori) in a plasmid do?

• It attaches the plasmid to the cell membrane

• It tells the plasmid where to begin replication

• It marks the end of the plasmid

• It cuts the DNA

What is a promoter site in a plasmid?

• A site that replicates DNA

• A green light that allows gene transcription

• A protective layer around the plasmid

• A site that degrades foreign DNA

How can plasmids be introduced into cells?

• Through electroporation

• Through digestion

• Through osmosis

• Through photosynthesis

What is a multiple cloning site?

• A storage area for extra DNA

• A site that clones the host cell

• A segment of DNA with several restriction sites

• A site that produces multiple plasmids

What advantage do plasmids often provide to bacteria in nature?

• Ability to fly

• Antibiotic resistance

• Increased size

• Ability to produce light

What is the purpose of inserting a GFP expressing gene into a plasmid?

• To enhance photosynthesis

• To produce antibiotics

• To increase cell size
