PROBLEM: The Hoecht stain binds to the minor groove of this molecule, forming G-quadruplexes. The ratio of nitrogen isotopes in this molecule, which exists in A, B, and Z forms, was measured in the Meselson-Stahl experiment to give evidence for its semiconservative replication. It winds around proteins called histones, and Okazaki fragments are formed when its namesake enzyme travels from the 5-prime to 3-prime direction of this molecule adding nucleotides. For 10 points, name this molecule that carries the genetic information of living organisms.

SOLUTION: Science

PROBLEM: In political thought, this man contributed a comparison of socialism, anarchism, and syndicalism, three of the titular Roads to Freedom. In another work sometimes viewed as a sequel to his What I Believe, he critiqued organized religion and as a whole, writing that "No one can sit at the bedside of a dying child and claim to believe in God" in an attempt to explain Why I Am Not a (*) Christian. Other works by this man include one written with Alfred North Whitehead, in which he explained the whole of mathematics in terms of logical expressions. For 10 points, name this modern British philosopher who wrote Principia Mathematica.

SOLUTION: Social Science

PROBLEM: In the middle layers of this structure, amacrine, bipolar, and horizontal cells work together to produce a graded response to synaptic input from receptors, which they transfer to the outermost layer of ganglion cells, neurons whose axons constitute the output from this structure to the brain via the second cranial nerves. The innermost layer is known as the pigment epithelium, and serves to prevent backscattering of light. FTP, name this structure of the eye that also has two types of photosensitive receptor cells, commonly referred to as rods and cones.

SOLUTION:
Science
