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.

Watch the demonstration video on nucleic acid quantification on the NanoDrop spectrophotometer: https://cutt.ly/bio150dnaquantification Note: the video is entitled RNA but the method is identical for DNA quantification. 1. Protocols in isolating DNA often involve the use of two kinds of ethanol, 100% ethanol and 70% ethanol, in succession. What happens during these steps and why are they essential?2. Spectrophotometric detection of nucleic acids require readings at wavelengths of 260nm, and 280nm. What is the significance of these wavelengths?
