TASK DEFINITION: In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: An RNA polymerase from one of these organisms is commonly used in in vitro transcription experiments, and one well-studied example of these organisms uses the Q antiterminator to transcribe its structural components. Benzer's rII system uses these organisms for single-nucleotide mutation mapping, and the Phi-X-174 example of these organisms was the first to have its genome (*) sequenced. These organisms carry genetic information between cells in transduction. These organisms were labeled with 32P and 35S in the experiment that showed that DNA is the substance that stores genetic information, performed by Hersey and Chase. These organisms use their tail proteins as an injection mechanism. For 10 points, name these viruses that infect bacteria.

SOLUTION: Science

PROBLEM: The electron dipole moment of this particle is at most three times ten to the negative 26th, and would violate CPT-symmetry if it is non-zero. This particle has a half-life of 881 seconds, and can break up into a proton, an electron and an electron antineutrino via beta decay. This particle is composed of one (*) up and two down quarks, and nuclear fission is initiated by the bombardment of this particle. The number of this particle dictates what isotope an atom is, and they have mass roughly equal to that of a proton. James Chadwick discovered, for ten points, what particle found in the nucleus, which, as its name suggests, has a net charge of zero

SOLUTION: Science

PROBLEM: A student of Johannes Muller, he began his career in the mid-nineteenth century, studying the connection between nerve fibers and cells and inventing the myograph to measure the speed of nerve impulses. His more lasting accomplishments were in the area of physics, where his work on magnetic fields and current led to Maxwell's development of the displacement current and he served as mentor to Planck. FTP, name this postulator of the electron and the conservation of energy.
