Biоinfоrmаticiаns аt GMU cоmpared three positions in a collection of DNA sequences and found: A, C, G, and T in position 1 C and G in position 2 G in position 3 Assuming that the bases observed at each position are equally likely, we can compute the uncertainty , where is the number of different bases observed at a given position. Calculate the uncertainty of each position, then rank the positions from greatest to least uncertainty. Briefly explain why their uncertainty values differ.
