MAT243 Project #3

MAT 243: Discrete Math Structures Project 3 Sequencing Sequences of numbers are a useful mathematical tool for exploring transitions and trends. Sequences of symbols create words, and sequences of words create languages, both Human and Computer. While sequences of nucleotides create DNA, which in turn create new sequences of nucleotides called RNA, which in turn creates sequences of amino acids called proteins, which in turn create, among other things, humans that create, among other things, computers. The quest to identify this "Source Code of Life" quickly became the focus of a great deal of science over the years, not to mention computing power. One method involves the use of certain enzymes that break the nucleotide chains at a specific chemical bond, and then analyzing the resulting fragments to determine the original structure. (The actual methods involved are in some ways harder than the problem in the Project, since you do not always know the sequence of the fragments, only their length. And in some ways much easier, since you have some idea of the count of each fragment contained in the original) For this project you will use the given information and a bit of logic to find an RNA sequence. You should not have to do any outside research, but feel free to explore the topic in greater depth. If you do any external research be sure to properly cite your sources. If you work with another student(s), please include their names) in the write-up as well. If you use any electronic resources to help you track the possible sequences or perform calculations, name them in the report, and include sample calculations in the case of something like a spreadsheet) or sample code (in the case of a programming language) You do not need to include the actual, executable program in the report Suppose that when an enzyme that breaks RNA chains after each G link is applied to a 12-link chain, the fragments obtained are CG, UG, and AUAG, And when an enzyme that breaks RNA chains after a Cor U link is applied, the fragments obtained are U, AG, GC, GU, and GAU. Can you determine the entire RNA sequence from these two sets of fragments? If not, why not? Would it help to know exactly how many of each fragment you have?

Answer 1

Ans:

• No, The entire RNA sequence cannot be determine.
• It's not possible as the least number of G-link brake fragments.
