A piece of DNA is cut into four fragments as shown below. A solution containing the four fragments is placed in a single well at the top of an agarose gel. Using the information given below, draw (below the well) how you think the fragments will be aligned on the gel following electrophoresis. Label each fragment with its corresponding letter. Remember, each band on the gel will be the same width, equal to the width of the well at the top of the gel. These should all be in one lane. What is it about the chemistry of DNA that causes it to be uniformly negatively charged?
