• Gel electrophoresis

What size DNA fragments travel through the gel the fastest?

• Larger fragments

• Smaller fragments

• Medium-sized fragments

What can be determined about the DNA in bands I and II?

• Band I contains a longer DNA sequence than band II.

• The DNA bands have the same DNA sequence

• The DNA bands are the same size

• Band II contains a longer DNA sequence than band I.

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
