DNA extraction

what is DNA extraction

• DNA extraction is the process of isolating DNA from cells or tissues.
• DNA extraction is the process of removing DNA from the body.
• DNA extraction is the process of creating DNA from scratch.
• DNA extraction is the process of analyzing DNA samples.

what is PCR

• Polymerase Chain Replication
• Polymerase Chain Reaction
• Protein Chain Reaction
• Polymerase Chain Reagent

What does PCR do?

• Creates multiple copies of DNA quickly.

• Destroys proteins in DNA so it doesn't cause diseases like, amylolysis.

• Creates multiple strands of DNA that don't exist.

• Moves DNA from the cell for studying, via electrical impulse.

What do restriction endonucleases do?

• They synthesize DNA.

• They modify DNA structure.

• They repair DNA damage.

• They cleave DNA at specific sites.

What are recognition sites?

• DNA sequences where restriction enzymes bind and cut.

• RNA sequences where restriction enzymes bind and cut.

• Lipid sequences where restriction enzymes bind and cut.

• Protein sequences where restriction enzymes bind and cut.

What is restriction digestion?

• Cutting RNA into smaller fragments using restriction enzymes.

• Amplifying DNA using restriction enzymes.

• Synthesizing DNA using restriction enzymes.

• Cutting DNA into smaller fragments using restriction enzymes.
