DNA fingerprinting works because....

• All organisms contain RNA

• The most important genes are different among most people

• No two people, except identical twins, have exactly the same DNA

A method of separating molecules, such as DNA, according to their size and electrical charge.

• Electrophoresis

• DNA Fingerprint

• DNA Probe

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

• DNA is negatively charged so attracted to the positive end of the unit

• DNA is positively charged to attracted to the negative end of the unit

• the agarose gel in negatively charged

• the agarose gel is positively charged

In gel electrophoresis, the largest DNA fragment will appear

• closest to the starting wells
• farthest from the starting wells
• three quarters away from the starting wells
• it depends on how many fragments there are

DNA fingerprinting works because

• Most genes are dominant
• All organisms contain RNA
• The most important genes are different among most people
• No two people, except identical twins, have exactly the same DNA 

A molecule that cuts a DNA molecule at a specific, base sequence.

• Allele

• Restriction Enzyme

• DNA Probe

Which of the following best describes a DNA molecule?

• double helix
• contains ribose
• made of amino acids
• contains Uracil
