TASK DEFINITION: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
PROBLEM: Polycomb gene silencing requires histone methyltransferase activity of Polycomb repressive complex 2 (PRC2), which methylates lysine 27 of histone H3. Information on how PRC2 works is limited by lack of structural data on the catalytic subunit, Enhancer of zeste (E(Z)), and the paucity of E(z) mutant alleles that alter its SET domain. Here we analyze missense alleles of Drosophila E(z), selected for molecular study because of their dominant genetic effects. Four missense alleles identify key E(Z) SET domain residues, and a fifth is located in the adjacent CXC domain. Analysis of mutant PRC2 complexes in vitro, and H3-K27 methylation in vivo, shows that each SET domain mutation disrupts PRC2 histone methyltransferase. Based on known SET domain structures, the mutations likely affect either the lysine-substrate binding pocket, the binding site for the adenosylmethionine methyl donor, or a critical tyrosine predicted to interact with the substrate lysine epsilon-amino group. In contrast, the CXC mutant retains catalytic activity, Lys-27 specificity, and trimethylation capacity. Deletion analysis also reveals a functional requirement for a conserved E(Z) domain N-terminal to CXC and SET. These results identify critical SET domain residues needed for PRC2 enzyme function, and they also emphasize functional inputs from outside the SET domain.

PROBLEM: The deflated Giants traveled to Minnesota to take on the Vikings. Already eliminated from the playoffs due to Washington beating Philadelphia the night before to secure the NFC East for the first time since 2012, they were without their star wide receiver Odell Beckham Jr. as he was suspended for his actions in a Week 15 loss against Carolina. The Vikings stingy defense put pressure on Eli Manning all game, forcing Tom Coughlin to bench Manning after three interceptions. The Giants defense was not a factor as they failed to contain the Vikings rushing attack all game long. Linebacker JT Thomas was ejected from the game in the 4th quarter for throwing a punch. The loss of Beckham was too steep to overcome and the Giants wound up losing 49-17, dropping to 6-9.

SOLUTION: Which team won the game?
