Genetic Testing and DNA Sequencing Technologies

Genetic science is transforming healthcare, but understanding how we read the human genome can feel overwhelming. This course demystifies the core technologies behind modern DNA sequencing and clinical genetic diagnostics. You will transition from having a basic curiosity about DNA to understanding how laboratories sequence genomes, identify mutations, and apply these insights to personalized medicine. What you'll learn: Understand the foundational molecular biology principles behind DNA replication and genetic variation; Compare classic Sanger sequencing with modern Next-Generation Sequencing workflows; Explore clinical applications of genetic testing, including oncology, prenatal screening, and rare disease diagnosis; Analyze the basics of genomic data interpretation and how variant calling identifies mutations; Evaluate emerging technologies like long-read sequencing and liquid biopsies; Address ethical, legal, and privacy considerations in patient genomic data management. The course begins with essential genetic terminology and molecular fundamentals before guiding you through historical sequencing breakthroughs, high-throughput modern technologies, and real-world clinical scenarios. Designed for beginners, healthcare professionals looking to update their knowledge, or science enthusiasts, this course requires no prior background in genetics or biochemistry. Start reading today to build a strong foundation in the technologies shaping the future of medicine.
