== Genome browsers in sequence analysis ==

Genome browsers offer a non-code, user-friendly interface to visualize genomes and genomic segments, identify genomic features, and analyze the relationship between numerous genomic elements. The three primary genome browsers—Ensembl genome browser, UCSC genome browser, and the National Centre for Biotechnology Information (NCBI)—support different sequence analysis procedures, including genome assembly, genome annotation, and comparative genomics like exploring differential expression patterns and identifying conserved regions. All browsers support multiple data formats for upload and download and provide links to external tools and resources for sequence analyses, which contributes to their versatility.<ref>{{cite journal |last1=Wang |first1=Jun |last2=Kong |first2=Lei |last3=Gao |first3=Ge |display-authors=2 |title=A brief introduction to web-based genome browsers |journal=Briefings in Bioinformatics |date=July 2012 |volume=14 |issue=2 |pages=131–143 |doi=10.1093/bib/bbs029 |pmid=22764121 |url=https://doi.org/10.1093/bib/bbs029}}</ref><ref>{{cite book |last1=Pevsner |first1=J. |title=Bioinformatics for DNA Sequence Analysis |chapter=Analysis of Genomic DNA with the UCSC Genome Browser |series=Methods in Molecular Biology |date=February 2009 |volume=537 |pages=277–301 |publisher=Humana Press |doi=10.1007/978-1-59745-251-9_14 |pmid=19378150 |isbn=978-1-59745-251-9 |chapter-url=https://doi.org/10.1007/978-1-59745-251-9_14}}</ref>
