[EX Q]: One protagonist in this novel spends a summer with the wife of Colonel Forster, and that character's aunt and uncle have the surname Gardiner. One character in this novel initially rejects a marriage proposal by Mr. Collins, while her sister is romanced by Mr. Bingley, and another romance in this novel is initiated by the master of Pemberley, Mr. Darcy.

[EX A]: Literature

[EX Q]: Notably, one of these entities is absent in the Leishmania mexicana GPI8 protein, and abnormally low numbers of pericytes occur if one is missing from PDGF. Binding of 14-3-3 proteins to GABAB ["Gabba-sub-bee"] receptors does not occur when two arginines are mutated to alanine in one of these entities, which also binds to the COPI complex. They are usually C-terminal signals, and a common mammalian one consists of the amino acids lysine, aspartate, gluatamate, and leucine, or KDEL. hnRNP C proteins contain one of them that allows them to override nuclear export signals. For 10 points, name these signals important in directing proteins to the correct membranes, most often used to prevent a protein's export from the endoplasmic reticulum. 
[EX A]: Science

[EX Q]: They are 1,2-dipolar species of the type RmX+ - Y-Rn. If X is a saturated atom from the first row of the periodic table, then this type of compound is represented by a charge-separable form, but if X is an unsaturated atom doubly bonded to another first row element Z, the negative charge on Y may be stabilized by a pi conjugation. Defined as compounds in which an anionic site Y- is attached directly to a heteroatom X+ carrying a formal positive charge these are, FTP, what compounds whose phosphonium variety is also known as the Wittig reagent
