DNA sequencing is a foundational technology in modern biology, enabling scientists to determine the precise order of nucleotides within a DNA molecule. By decoding genetic information at high resolution, sequencing technologies have transformed fields such as medical diagnostics, genomics research, biotechnology, and personalized medicine.

What Is DNA Sequencing?

DNA sequencing is the process of identifying the exact sequence of adenine (A), thymine (T), cytosine (C), and guanine (G) in a DNA strand. This genetic blueprint provides critical insights into gene function, genetic variation, and molecular mechanisms underlying health and disease.

Today, advanced DNA sequencing technologies allow rapid, accurate, and cost-effective analysis of genomes, genes, and targeted regions.

Types of DNA Sequencing Technologies

Modern DNA sequencing methods include several widely used approaches:

• Sanger Sequencing: Ideal for small-scale projects and sequence verification.

• Next-Generation Sequencing (NGS): Enables high-throughput sequencing for whole genomes, exomes, and targeted panels.

• Long-Read Sequencing: Supports structural variant detection and complex genome analysis.

• Targeted DNA Sequencing: Focuses on specific genes or regions of interest for diagnostics and research.

Each method is selected based on accuracy requirements, read length, throughput, and application goals.

Applications of DNA Sequencing

DNA sequencing is used across diverse scientific and clinical fields, including:

• Genetic Disease Diagnosis

• Cancer Genomics and Oncology Research

• Infectious Disease Identification

• Pharmacogenomics and Precision Medicine
