Question: 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.

Answer: Science


Question: A maximum independent set for this data structure can be found in linear time by adding alternating levels. In this structure, any two vertices or nodes must be connected by a single simple path, and thus it is connected and acyclic. By using (*) union-find with disjoint sets, one type of this structure containing all the vertices of a connected graph can be constructed. One variety of this data structure can be used to easily implement a binary search. This structure also comes in red-black and self-balancing-binary varieties. For 10 points, identify this data structure from computer science, a hierarchical graph in which "leaf" nodes ultimately flow from a "root" node.

Answer: Science
