DNA Sequencing and Analysis

DNA sequencing and analysis involve determining the precise order of nucleotides within a DNA molecule to uncover genetic information essential for research and clinical applications. With the advent of next-generation sequencing (NGS), scientists can decode entire genomes rapidly and cost-effectively, allowing high-resolution insights into genetic variations, disease-associated mutations, and molecular pathways. Sequencing data analysis includes alignment, variant calling, annotation, and bioinformatic interpretation to derive meaningful conclusions about an organism’s genetic makeup. In precision medicine, sequencing enables the identification of actionable biomarkers, guiding personalized therapies for cancer, rare diseases, and infectious disorders. Its applications also extend to evolutionary biology, microbiome studies, pharmacogenomics, and gene-editing research.
