Genome data analysis involves several systematic steps to transform raw sequencing data into meaningful biological information. The process begins with data acquisition, where DNA is extracted from the organism of interest and sequenced using technologies like Illumina, PacBio, or Oxford Nanopore. The raw sequence reads obtained are then subjected to quality control, which includes removing low-quality reads, adapter sequences, and sequencing artifacts using tools such as FastQC and Trimmomatic. Next is read alignment or assembly. In alignment, reads are mapped to a reference genome to identify their correct positions using algorithms
