Dot Plot Sequence Analysis: How to Read Repeats, Gaps, and Similarity
Learn how a sequence dot plot works, what diagonal patterns can suggest, how window and threshold settings affect noise and sensitivity, and when to follow the visual pattern with an alignment.
Local Protein Alignment: How Smith-Waterman Finds the Best Matching Region
Learn when local protein alignment is more appropriate than an end-to-end comparison, how Smith-Waterman defines the matching region, and how to interpret score, coordinates, identity, and gaps without overclaiming.
Global Sequence Alignment Explained: When Needleman-Wunsch Is the Right Tool
Learn when end-to-end protein alignment is appropriate, how it differs from local alignment, why substitution matrices and gap penalties change the result, and how to interpret score and identity responsibly.
How to Generate Random Protein Sequences for Reproducible Bioinformatics Testing
Choose the right random-sequence model, distinguish uniform generation from shuffling, preserve the generated FASTA and metadata, and avoid treating synthetic controls as natural proteins.
