DNA Sequence Alignment and Visualization with "SequenceAlignment" Package In bioinformatics, sequence alignment plays a crucial role in comparing biological sequences, especially DNA sequences. It helps in identifying similarities, differences, and evolutionary relationships between sequences. In this blog, we’ll explore how to use the SequenceAlignment R package for performing sequence alignments, visualizing the results with plots like barplots and heatmaps , and analyzing DNA sequences against multiple reference sequences stored in FASTA files. What is Sequence Alignment? Sequence alignment is the process of comparing two or more biological sequences (e.g., DNA, RNA, or proteins) to identify regions of similarity or difference. In DNA sequence alignment, the sequences are compared to see how closely they match, which can provide insights into genetic similarities, mutations, or evolutionary trends. The SequenceAlignment Package The SequenceAlignment package is a powerf...
