Q: Imetelstat, a potential new cancer therapy agent, works by targeting the enzyme that repairs these structures. Blackburn, Greider, and Szostak received the 2009 Nobel Prize for determining the role of these structures, which typically adopt a G-quadruplex shape. The shortening of these structures explains the Hayflick limit to cell division and is the basis for the cellular theory of aging, and that shortening of these structures can lead to cell senescence or apoptosis. Consisting of thousands of TTAGGG repeats in humans, name these end sequences of chromosomes that prevent genes from being lost during DNA replication.

A: Science

Q: This ruler attacked the custom of smoking in his essay ""A Counterblast to Tobacco,"" and he wrote about witchcraft in his book on demonology. Anthony Weldon dubbed this king ""the wisest fool in all of Christendom. "" This ruler angered Parliament by playing favorites, such as by making George Villiers the Duke of Buckingham. During this man's reign, Guy Fawkes attempted to destroy parliament in the Gunpowder plot. For 10 points, name this son of Mary, Queen of Scots, the successor to Elizabeth I and first Stuart monarch.

A: History

Q: Carmichael proved that large ones of these do not share prime factors with other ones, and Wall-Sun-Sun primes are necessarily these. Matiyasevich's disproof of Hilbert's tenth problem relied on these values to show that Diophantine equations have solutions that can grow exponentially, and a pair of them give the Euclidean algorithm its worst-case runtime. Their generating function is x divided by 1 minus x minus x squared, and every positive integer can be written as the sum of non-consecutive ones of these according to Zeckendorf's theorem. The Lucas numbers obey a similar rule as them, and one formula for generating them relies on the Golden Ratio, known as Binet's formula. Defined recursively by summing the previous two numbers in the sequence, for 10 points, name these numbers that begin 1, 1, 2, 3, 5
