- 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. FIGURE 8.7 Nucleotides can be joined together to form chains caled polynucleotides. Polynucleotides are polar molecules with a 5 end (at the phosphate group) and a 3 end (at the sugar group). An RNA polynucleotide is shown at the left, and a DNA polynucleotide is shown at the right.For the following sequence of amino acids, serine-valine-lysine-leucine, which of the choices below is the correct order for the nucleotide base sequence in DNA?

B) From the information you have been given, why is it not possible to accurately write out the DNA sequence as it would really be found in the genome? (ie, what you wrote down in part A is NOT necessarily what the DNA sequence would really look like if we could examine the chromosome directly - why? And no this has nothing to do with the 30 nucleotides that aren’t written out or the mutated base). Your answer should be 1-2 sentences maximum.
