De novo genome sequencing involves the comprehensive characterization of an organism's genome without reliance on a pre-existing reference sequence. This process utilizes bioinformatics algorithms to assemble raw sequences into a complete genomic map, which subsequently serves as the foundation for structural and functional annotation, as well as comparative genomics studies.
Long-read sequencing technologies, notably PacBio and Nanopore, are distinguished by their ability to generate extensive read lengths ranging from 10 kb to several megabases. By efficiently producing high-fidelity data (>Q20), these platforms enable the robust assembly of both simple and highly complex genomes.
Analysis
