DNA Sequencing and Genetic Testing Fundamentals

The field of genomics is transforming healthcare, personalized medicine, and biotechnology at an unprecedented pace. Understanding how we read and analyze genetic code is no longer just for lab scientists—it is essential knowledge for anyone entering the health, tech, or life science sectors. This text-based course guides you through the fundamental science, technologies, and clinical applications of modern genetic testing. You will transition from understanding basic DNA structure to evaluating complex sequencing workflows and interpreting genomic data reports. What you'll learn: Understand the fundamental biology of DNA, genes, and the core concepts of genetic inheritance; Compare traditional Sanger sequencing with modern Next-Generation Sequencing (NGS) and long-read technologies; Explore the workflow of clinical genetic testing, from sample preparation to variant calling; Analyze how genomic data is interpreted to identify disease-causing mutations and variants of uncertain significance; Examine the ethical, legal, and privacy considerations surrounding personal genomic data. The course begins with essential terminology and the foundational science of genetics before moving into step-by-step written breakdowns of sequencing methodologies and real-world clinical applications. Designed specifically for beginners, this course requires no prior background in molecular biology or bioinformatics. Start reading today to build a strong foundational knowledge of genetic sequencing technologies.
