Question
(6) Write the molecule or class of molecules described by each clue. If the clue describes more than one (type of) molecule, give an example of a molecule or class of molecules described by the clue (1 point each) (A) Molecule that "stores" genetic information, i.e. the molecule that genes are made of (B) A non-reducing sugar (provide one example of a compound in this category) (C) Nucleic acid base (nucleobase) present in DNA instead of uracil due to uracil's tendency to tautomerize (D) An amino acid residue likely to be found at the edge of a membrane spanning helix as well as to be involved in binding with galactose residues in oligosaccharides (E) Aldohexose: in its P-pyranose form, all of the heavy atom substituents on the ring are equatorial (F) Keto-hexose that, having the same configurations at carbons 3-5 as glucose, can be produced from glucose via an enediol intermediate (G) Hetero-polysaccharide whose high negative charge density increases the affinity of anti-thrombin (which it binds) to the positively charged thrombin molecule (H) Extended (non-substituted) poly-saccharide chain with structure reminiscent of a protein ß-strand; as in fibrous proteins like silk fibroin, the strands form rolled sheets () An amino acid residue likely to be found at the edge of a membrane spanning helix as well as to be phosphorylated by an activated insulin receptor A molecule (eg. provide an example of such a molecule) that reacts with Benedict's reagent to form a red precipitate (J)Explanation / Answer
A) Deoxyribonucleic acid (DNA)
B) Sucrose
C) Thymine
D) Proline
E) Beta-D Glucose
F) D-Fructose
G) Heparin
