Which base will hydrogen-bond with uracil within an RNA molecule? Draw the structure of this base pair.
Answer to relevant QuestionsTautomers are molecules that differ in the position of a hydrogen atom. A tautomeric fonn of thymine has the structure If this tautomer, rather than the stable form of thymine, were present in a strand of DNA during ...Sorbic acid is used to prevent mold and fungus growth in some food products, especially cheeses. The systematic name for sorbic acid is 2,4-hexadienoic acid. Draw structures for the four geometric isomers of sorbic acid. A urethane linkage occurs when an alcohol adds across the carbon—nitrogen double bond in an isocyanate: Polyurethanes are formed from the copolymerization of a diol with a diisocyanate. Polyurethanes are used in foamed ...The reaction to form a phosphate-ester linkage between two nucleotides can be approximated as follows: Would you predict the formation of a dinucleotide from two nucleotides to be a spontaneous process? Using one of the Lewis structures for benzene (C6H6), estimate ∆Hf° for C6H6(g) using bond energies and given that the standard enthalpy of formation of C(g) is 717 kj/mol. The experimental ∆H,° value for C6H6(g) is 83 ...
