Scientists believe polysaccharides played little role, if any, in chemical evolution. Which of the following is not true of polysaccharides, leading scientists to discount them as the first life-forms?
A) They are incapable of catalyzing chemical reactions.
B) Because there is no complementary pairing between monosaccharides, they cannot provide the information for copying themselves.
C) The formation of glycosidic linkages between monosaccharides has been observed only with complex enzymes that would have come after chemical evolution—during biological evolution.
D) Polysaccharides are polymers, meaning they contain many monomer subunits. Polymers have never been observed to form, in any type of molecule, under laboratory conditions.
