Question: Context: Selenoproteins are an elite group of proteins containing a rare amino acid, selenocysteine (Sec), encoded by the codon, UGA. In eukaryotes, incorporation of Sec requires a Sec insertion sequence (SECIS) element, a stem-loop structure located in the 3'-untranslated regions of selenoprotein mRNAs. Here we report identification of a noncanonical form of SECIS element in Toxoplasma gondii and Neospora canine, single-celled apicomplexan parasites of humans and domestic animals. This SECIS has a GGGA sequence in the SBP2-binding site in place of AUGA previously considered invariant. Using a combination of computational and molecular techniques, we show that Toxoplasma and Neospora possess both canonical and noncanonical SECIS elements. The GGGA-type SECIS element supported Sec insertion in mammalian HEK 293 and NIH 3T3 cells and did so more efficiently than the natural mammalian SECIS elements tested. In addition, mammalian type I and type II SECIS elements mutated into the GGGA forms were functional but manifested decreased Sec insertion efficiency. We carried out computational searches for both AUGA and GGGA forms of SECIS elements in Toxoplasma and detected five selenoprotein genes, including one coding for a previously undescribed selenoprotein, designated SelQ, and two containing the GGGA form of the SECIS element. In contrast, the GGGA-type SECIS elements were not detected in mammals and nematodes. As a practical outcome of the study, we developed pSelExpress1, a vector for convenient expression of selenoproteins in mammalian cells. It contains an SBP2 gene and the most efficient tested SECIS element: an AUGA mutant of the GGGA-type Toxoplasma SelT structure. 
 Question: What is the name of the stem loop present in the 3' end of genes encoding for selenoproteins?

Answer: secis


Question: Context: In the 19th century, a Grande Dame (Jeanne Moreau) summons The Brothers Grimm to her palace, where the brothers discuss their interpretation of the Cinderella story and notice a painting displayed in the room. The Grande Dame shows the brothers a glass slipper and tells them the story of Danielle de Barbarac, the true story of Cinderella. In 16th-century France, widower Auguste de Barbarac (Jeroen Krabbe), father of eight-year-old Danielle, marries Rodmilla de Ghent (Anjelica Huston), a wealthy baroness with two young daughters, Marguerite and Jacqueline, but he dies of a heart attack shortly afterwards. Before dying, Auguste's last words are directed to Danielle, which causes the Baroness to envy Danielle and treat her miserably for the next ten years. While Marguerite (Megan Dodds) is hostile and cruel to Danielle, Jacqueline (Melanie Lynskey) is kinder and more respectful to her, though she often stays out of the crossfires to keep the peace. By the time Danielle (Drew Barrymore) is eighteen, the estate has fallen into decline, as the Baroness has no interest in farming and wishes to get back to court as soon as possible. Danielle has been reduced to a servant in her own home, waiting on her stepmother and stepsisters, and clinging to her father's last gift, a copy of Thomas More's Utopia. While collecting apples, Danielle sees a man stealing her father's horse and unseats him with an apple. When she recognizes he is Prince Henry (Dougray Scott), she abases herself. He gives her a bag of gold in exchange for her silence. She decides to use the money to rescue their servant, Maurice (Walter Sparrow), whom the Baroness has sold to pay her debts. Henry's escape from the duties of court is foiled when he encounters a band of gypsies robbing an old man. He learns that the old man is Leonardo da Vinci (Patrick Godfrey), who has been summoned to court. Henry chases a thief and returns the Mona Lisa to da Vinci, then returns with him. Meanwhile, Danielle dresses as a noblewoman and leaves to buy back Maurice, but the guards refuse, saying he is being deported to the Americas. She argues for his release and, when Henry overhears, he orders Maurice's release. Intrigued by Danielle's mysterious identity, and amazed by her eloquence and passionate pleas, he begs for her name. Danielle gives Henry the name of her mother, "Comtesse Nicole de Lancret", who died giving birth to Danielle. King Francis (Timothy West) and Queen Marie (Judy Parfitt) tell Henry that he must choose a bride before the upcoming masquerade ball, or he will have to wed the Spanish princess Gabriella. All the noble families receive an invitation and Danielle initially believes she is included. When collecting truffles, she meets Henry by the river in the company of da Vinci. Henry and Danielle engage in a lively debate before Danielle runs off after she notices Jacqueline searching for her. Henry invites her to visit the library of a nearby monastery. On the way home, they are ambushed by the gypsies, who are amused by Danielle's outrage and agree to release her with whatever she can carry. When she picks up Henry and begins to walk away, the gypsies offer them a horse. Henry and Danielle spend the night at the gypsy camp, sharing their first kiss and arranging to meet again. The next morning, Danielle catches the Baroness and Marguerite stealing her mother's dress and slippers for Marguerite to wear to the ball. After Marguerite insults Danielle about her mother's death, she punches Marguerite in the face and chases her around the manor until Marguerite threatens to throw Utopia into the fireplace. Danielle returns her mother's slippers to the Baroness in exchange for the book but Marguerite burns it in the fire anyway in an act of spite. After Danielle is punished by whipping, Jacqueline tends to her wounds and condemns Marguerite for insulting Danielle's deceased mother. When Danielle meets Henry later, she wishes to tell him the truth, but is afraid he will reject her after he confesses his love. During 
 Question: who plays Jacqueline?

Answer: melanie lynskey


Question: Context: A personal journey into the heart of the Killing FieldsOne of the most harrowing and compelling personal documentaries of our time, ENEMIES OF THE PEOPLE exposes for the first time the truth about the Killing Fields and the Khmer Rouge who were behind Cambodias horrific genocide. More than simply an inquiry into Cambodias experience, however, ENEMIES OF THE PEOPLE is a profound meditation on the nature of good and evil, shedding light on the capacity of some people to do terrible things and for others to forgive them.Winner of a dozen top documentary festival awards, including a Special Jury Prize at Sundance and the Grand Jury Award at the Full Frame Documentary Festival, this is a riveting film that takes audiences as close to witnessing evil as they are ever likely to get. It is also a personal journey into the heart of darkness by journalist/filmmaker Thet Sambath, whose family was wiped out in the Killing Fields, but whose patience and discipline elicits unprecedented on-camera confessions from perpetrators at all levels of the Khmer Rouge hierarchy. This is investigative journalism of the highest order.In 1974, Thet Sambaths father became one of the nearly two million people who were murdered by the Khmer Rouge when he refused to give them his buffalo. Sambaths mother was forced to marry a Khmer Rouge militiaman and died in childbirth in 1976, while his eldest brother disappeared in 1977. Sambath himself escaped Cambodia at age 10 when the Khmer Rouge fell in 1979.Fast forward to 1998, and Sambath, now a journalist, got to know the children of some senior Khmer Rouge cadre and gradually earned their trust. Then, for a decade, he spent weekends visiting the home of the most senior surviving leader, Nuon Chea, aka Brother Number Two under Pol Pot. But he never used to say anything different from what he told Western journalists, says Sambath, I was low-ranking, I knew nothing, I am not a killer. Then one day he said to me Sambath, I trust you, you are the person I would like to tell my story to. Ask me what you want to know. For the next five years he told me the truth, as he saw it, including all the details of killing.Sambath also won the confidence of lower-level Khmer Rouge soldiers, now ordinary fathers and grandfathers, who demonstrated to him how they slit peoples throats. For these murderers, it was the first time they admitted what they had done. He taped their interactions and discussions about the killings, and together with British documentarian Rob Lemkin they created this landmark film.For Sambath, it has been an ongoing, lifelong personal journey to discover what was behind such horror; he neglected both his family and his own happiness in the search for truth with hope of reconciliation. ENEMIES OF THE PEOPLE is at once a cinematically beautiful, chillingly insightful, and deeply personal piece of documentary filmmaking.
