Question: Extract the answer to the question from the following context. Question: What is the difference between DNA and RNA? Context: Additionally, genes can have regulatory regions many kilobases upstream or downstream of the open reading frame. These act by binding to transcription factors which then cause the DNA to loop so that the regulatory sequence (and bound transcription factor) become close to the RNA polymerase binding site. For example, enhancers increase transcription by binding an activator protein which then helps to recruit the RNA polymerase to the promoter; conversely silencers bind repressor proteins and make the DNA less available for RNA polymerase.
Answer: the regulatory sequence

Question: Extract the answer to the question from the following context. Question: What has happened to indie rock? Context: Since the mid-2000s, the mainstreaming of bands like Wilco and Feist have pushed indie rock into the adult contemporary conversation. In the early 2010s, indie musicians like Imagine Dragons, Mumford & Sons, Of Monsters & Men, The Lumineers and Ed Sheeran also had indie songs that crossed over to the adult contemporary charts.
Answer: mainstreaming

Question: Extract the answer to the question from the following context. Question: water is gotten from? Context: A very small amount of water vapor inside a light bulb can significantly affect lamp darkening. Water vapor dissociates into hydrogen and oxygen at the hot filament. The oxygen attacks the tungsten metal, and the resulting tungsten oxide particles travel to cooler parts of the lamp. Hydrogen from water vapor reduces the oxide, reforming water vapor and continuing this water cycle. The equivalent of a drop of water distributed over 500,000 lamps will significantly increase darkening. Small amounts of substances such as zirconium are placed within the lamp as a getter to react with any oxygen that may bake out of the lamp components during operation.
Answer:
hydrogen and oxygen
