Deoxyribonucleotides a) Lack a hydroxyl group at position 2 of the sugar molecule b) Lack a hydroxyl group at position 3 of the base c) Lack a hydroxyl group at position 3 of the sugar molecule d) Lack a hydroxyl group at position 2 of the base
A) Draw the "standard" base pairs (A:T and G:C) but instead of using the most common form of each base, use the uncommon tautomer form of each base (i.e. imino A, imino C, enol G, enol T). Clearly indicate hydrogen bonds (an arrow from donor to acceptor will suffice). Be sure to include the “R” representing the pentose. B) The G:U "wobble" base pair can be formed between the most common tautomer forms of G & U. Another base pair with the same geometry/pairing/orientation can be formed between G & T. Can you create a "wobble" base pair between the uncommon enol tautomer forms of G & T? Like the "wobble" G:U base pair in the Lecture 1 slides, this enol-based "wobble" G:T base pair must have at least two hydrogen bonds. If possible, draw such a base pair, and note any important differences from the non-enol G:U/T wobble. If it is not possible to draw such a base pair, explain why.
Let’s consider histidine as a free amino acid in aqueous solution. a) Draw the most likely structure of histidine under biochemical standard state conditions. b) Given that free histidine has the following three pKa values, assign each to its corresponding acidic hydrogen or conjugate base in your structure from part a). pKa1 = 1.7; pKa2 = 6.2; and pKa3 = 9.1 c) For each pKa, give the corresponding expression for the equilibrium constant. It helps to write out the chemical equation for each. d) Create a speciation diagram for histidine by plotting Xi vs pH from pH = 4 to pH = 8 where Xi is the mole fraction of the two histidine species involved in the K2 equilibrium in part c).
