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

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 

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

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

• 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 charges the DNA strands

What is the purpose of gel electrophoresis?

• helps cut DNA

• count the genes in DNA

• separates DNA based on size

• allows for an exact replicated organism

This is the process of creating a unique image of an individual's alleles based on their size and using that image to identify an individual's DNA

• Gel Electrophoresis

• Genetic Engineering

• DNA Fingerprinting

This is the practice of cutting DNA and separating it by the size of the pieces
