- Using Figures 8.7 and 8.9 as a guide, draw a dinucleotide composed of C and A. Next to this, draw the complementary dinucleotide in an antiparallel fashion. Connect the dinucleotides with the appropriate hydrogen bonds. FIGURE 8.9 The two polynucleotide chains in DNA run in opposite directions. The left strand runs 5 to 3, and the right strand runs 3 to 5. The base sequences in each strand are complementary. An A in one strand pairs with a T in the other strand, and a C in one strand is paired with a G in the opposite strand.

- 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?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 if you had two different DNA fragments that were exactly the same length as measured in base-pairs. Would it be possible to distinguish them using this type of electrophoresis?
