Protein sequence alignment is a fundamental bioinformatics method for comparing proteins, identifying conserved regions, detecting homologues, studying protein families and investigating evolutionary relationships.
Gene-tree/species-tree reconciliation compares gene trees with species trees to reconstruct evolutionary events such as gene duplication and gene loss. Learn the principles, workflow, applications, limitations, and role of reconciliation in comparative genomics and phylogenetics.
Phylogenetic analysis of homologous genes helps reconstruct evolutionary relationships among genes and gene families. Learn about sequence selection, multiple sequence alignment, phylogenetic methods, evolutionary models, branch support, gene trees, and major applications in comparative genomics.
Learn how gene families are identified using sequence similarity, protein domains, motifs, clustering, orthology, multiple sequence alignment, phylogenetics, and genomic context.
Gene trees and species trees describe different aspects of evolutionary history. Learn how they are constructed, why they can differ, and how duplication, gene loss, incomplete lineage sorting, horizontal gene transfer, and other processes influence evolutionary relationships.
Orthology inference identifies evolutionary relationships between genes using sequence similarity, gene families, phylogenetics, synteny, and computational methods. Learn the major approaches and their limitations.
Orthologs are homologous genes that diverged following speciation. Learn what orthologs are, how they differ from paralogs, and why they are important in comparative genomics, evolution, and genome annotation.
GenBank and RefSeq are important NCBI sequence resources with different purposes. Learn how their records, curation, redundancy, accession numbers, and applications differ.
BLAST is a widely used bioinformatics tool for finding similarities between DNA, RNA, and protein sequences. Learn how BLAST works, its major programs, applications, and role in sequence analysis.
BLAST and GenBank work together to make DNA sequence analysis easier. Learn how BLAST compares nucleotide sequences, how to evaluate BLAST hits, and how GenBank records help identify and interpret DNA sequences.
