Greedy motif search

WebPublic user contributions licensed under cc-wiki license with attribution required WebAug 15, 2024 · Our last topic in this segment is Greedy Motif Search. We'll now talk about a greedy algorithm, for solving the Motif Finding Problem. Given a set of motifs, we have already learned how to construct the consensus string. Now let's construct the count matrix where in every column we simply have counts for all nucleotides.

Three Approaches to Solving the Motif-Finding Problem

WebJun 18, 2024 · Create a consensus motif to score the level of conservation between all motifs in our data. Determine the probability of any possible motif occurring according our profile matrix.

WebDec 22, 2024 · 1. I'm looking for intuition for why a randomized motif search works. My current thinking is as follows: We are selecting many random kmers from our DNA sequences. The chosen kmers will bias the profile matrix to selecting kmers like them. Given any particular k-mer chosen, there are two possibilities: We've selected a meaningless …
