Unformatted text preview: (a) Describe the format of the le S 1 in words. What is the parent mass and charge of P ? (Note: Use the web to understand the .dta format.) (b) Identify the peptides in S 1 and S 2 using Mascot MS/MS ion search (http://www.matrixscience.com/search form select.html). Note that S 2 is a dicult example, so please use caution. Once the peptide is identied, give your own reasons for the identication being correct. Such reasons could include percentage of b-y ions matched, percentatge of total intensity explained, and so on. 3. (48pts.) Design and implement an algorithm perf which takes as input a binary character matrix, and constructs a perfect phylogeny if one exists. The output of the program should be a tree (described as a set of parent child relationships). Test your algorithm on the two data-sets provided. 4. (2pts.) What language did you use? How much time did you take to do the assignment? Who did you discuss your homework with?...
