WebSep 2, 2024 · The basis of sequence alignment lies with the scoring process, where the two sequences are given a score on how similar (or different) they are to each other. The pairwise sequence aligning algorithms require a scoring matrix to keep track of the scores assigned. The scoring matrix assigns a positive score for a match, and a penalty for a … WebAnd then we would align sequence 4 to the profile defined by sequence 1, 2, and 3, the alignment of sequence 1, 2, and 3. So really the guide tree determines the order of the alignment of the sequences to each other or the sequences to pre-existing profiles. So once we've got this, once we've reached this step, we can perform alignments.
