Draw i t copy the polynucleotide strand in figure 5.24a and label the bases g, t, c, and t, starting from the 5′ end. assuming this is a dna polynucleotide, now draw the complementary strand, using the same symbols for phosphates (circles), sugars (pentagons), and bases. label the bases. draw arrows showing the 5′ s 3′ direction of each strand. use the arrows to make sure the second strand is antiparallel to the first. hint: after you draw the first strand vertically, turn the paper upside down; it is easier to draw the second strand from the 5′ toward the 3′ direction as you go from top to bottom. level 3: synthesis/evaluat ion.
