Polymerase Chain Reaction

Gel Electrophoresis

Restriction Enzyme

Restriction Digestion

DNA is located in the (a) of human cells.

DNA has a ______ charge.

positive

neutral

negative

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

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

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

To create a DNA profile, the DNA must be copied multiple times. Which of the following is the process by which the DNA is copied?
