Restriction Enzymes & Gel Electrophoresis

In 1984, this British scientist developed a technique utilizing the variation in DNA sequences to identify individuals.

• Luois Pasteur

• Alec Jeffreys

• Doug Greene

• Dr. Kelly Gwaltney

This type of agent acts as molecular scissors that can cut DNA in specific location

• Guanine

• Gel Electrophoresis

• restriction enzymes

• RNA

Every individual’s DNA is unique

• True

• False

What is another name for restriction enzymes?

• molecular scissors

• bacterial cells

• phages

• Restriction endonucleases

An individual’s code determines the number of times the restriction enzymes will cut and the number and size of DNA pieces that will result.

• True

• False

DNA pieces can then be separated and compared using a process called

• gel electrophoresis

• DNA Puzzle Pieces

• RFLPs

• Agrose Gel

As DNA fragments move through during gel electrophoresis, their varying lengths propel them through an agarose gel at different speeds

• True

• False

The first restriction enzymes are produced naturally by bacteria.

• True

• False

The migration of charged particles under the influence of an electric field is called:

• restriction enzyme

• Phoresis

• Electro

• electrophoresis?

DNA is positively charged

• True

• False
