What is the primary purpose of using restriction enzymes in gel electrophoresis?

• It restricts the number of base pairs that can be tested in a sample.

• It makes the testing simpler by moving the strands into the gel faster.

• It allows the strands of DNA to be cut into various lengths for testing.

Gel electrophoresis separates DNA according to size. Which is true regarding movement of the DNA?

• The biggest pieces of DNA will move the shortest distance.

• The biggest pieces of DNA will move the greatest distance.

• The shortest pieces of DNA line up along the middle.

Which best describes recombinant DNA?

• DNA that has been deactivated by enzymes

• DNA found in organelles other than the nucleus

• Gene from one organism inserted into another

• Genes formed during sexual reproduction

Which substance is cut by restriction enzymes?

• DNA

• Carbohydrates

• Proteins

• Lipids

What causes DNA to move during a gel electrophoresis?

• A magnetic field
