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.

Q: A version of spectroscopy that is free of one form of this effect uses a standing wave to give radiation to a moving atom and is named for its two-photon transition. Due to this effect, atoms observe laser resonance leading to the phenomenon of optical molasses at its namesake cooling limit. Mossbauer spectroscopy uses this effect to modulate the energy of the incident gamma rays. An experiment that used a canal ray tube and a mirror to view light emissions was used to detect the transverse form of this effect, while its relativistic form involves changes equal to the square root of one plus beta over one minus beta. For 10 points, name this shift in the wavelength from a moving source that can be heard by an observer.

Q: This organelle's lamina helps support its shape. Some protists have both a macro and micro version of this organelle. One part of this organelle is the location of ribosome synthesis, while importins and exportins assist in transport in and out of this organelle. This organelle, whose envelope is continuous with the rough endoplasmic reticulum, has pores in its double membrane. Transcription occurs within this organelle, which disappears during mitosis as its chromatin assemble into chromosomes. For 10 points, name the control center of the cell.

Q: Kawada and Cohen used a combination of an HDAC6 inhibitor and a protease inhibitor to selectively kill cells infected with this virus, and cells infected with it show upregulated fgr tyrosine kinase. Expression of its nuclear antigens are controlled epigenetically through the Wp, Cp, and Qp promoters, and also encodes for a series of miRNAs near its BART and BHRF1 genes, the latter of which is a Bcl2 homologue. Its latent cycle is promoted by the transmembrane proteins LMP-1 and 2, and causes hairy leukoplakia in AIDS patients. Also responsible for post-transplant lymphoproliferation, this virus is associated with a disease that sees a translocation of c-myc and a starry sky appearance under an H&E stain, called Burkitt's lymphoma. For 10 points, name this herpesvirus that infects B-cells and commonly causes mononucleosis.
