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.

Spring O The nucleotides in one strand of DNA are held together by hydrogen bonds. The nitrogenous bases in one strand are held to the nitrogenous bases of the other strand by phosphodiester bonds. ules Purine nucleotides always form base pairs with other purines, and pyrimidine nucleotides always form base pairs with other pyrimidines. nments es O The diameter of a DNA molecule is the same along its entire length due to the specific complementary base pairing of the DNA. ouncements -le Question 5 1 pts millan Higher ation Media In the sequence 5'-TCCGGA-3', an available phosphate group would be found at the 5' end of the nucleotide labeled "T." ia Gallery aborations O True False neCoach Roster cussions No new data to save.
