Construct a table that organizes the following terms, end label the columns and rows.
Monosaccharides | Polypeptides | Phosphodiester linkages |
Fatly acids | Triacylglycerols | Peptide bonds |
Amino acids | Polynucleotides | Glycosidic linkages |
Polysaccharides | Ester linkages |
DRAW IT Copy the polynucleotide strand in Figure 3.27a 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′ → 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.
