In preparation for an electrophoresis procedure, restriction enzymes are added to DNA in order to

• convert the DNA into gel

• cut the DNA into fragments

• change the color of the DNA

• produce longer sections of DNA

Based on these results whose blood was found in the blood stain at the crime scene?

• Bob
• Sue
• John
• Lisa

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

Gel electrophoresis separates fragments of DNA by:

• Size/weight

• Genes

• Base pairs

• Electromagnetic charge

What are the proper complementary base-pairs?

• A--T and G--C

• A--G and C--T

• G--T and A--C

• A--C and T--G
