[EX Q]: In 1999, McIlroy created an adversary for this algorithm that guarantees that it will run in worst-case time. Its worst-case runtime can be avoided by switching to heapsort after a certain recursion depth, a construction known as introsort. Like mergesort, it is easily parallelizable, and its runtime can be decreased by first selecting the median of the unsorted input list. It was invented by C.A.R. Hoare, and its second phase is the partition function, which splits the original list into lists of elements that are greater or less than the chosen pivot value. For 10 points, identify this divide-and-conquer sorting algorithm which runs in big O of n log n time, named for its speed.

[EX Q]: Modified by the Sin3 complex, they have chaperones such as NAP-I and CAF-I while a variant of one of these named CENP-A generates new binding sites. Discovered by Kossel, these conserved proteins are replaced by protamines during spermatogenesis. Composed of a high proportion of positively charged amino acids, they have an N-terminal extension called a "tail" that can be acetylated. The linker type is not included in the octamer that consists of the core ones: H2A, H2B, H3, and H4. For 10 points, name these proteins that pack DNA in chromatin.
