NGS Explained: Next Generation Sequencing Step-by-Step

NGS (Next Generation Sequencing) can sequence a whole human genome in a single day, a process that took over 30 years with the Human Genome Project. This animation explains how Illumina sequencing and NGS work step-by-step, including library preparation, cluster generation, sequencing by synthesis, and how billions of DNA strands are sequenced simultaneously. You'll also learn how NGS compares to Sanger sequencing, how sequencing reads are filtered and mapped to a reference genome, and the key applications of NGS in research and medicine. Correction: 0:13:00 should read that 85% of the human genome was completed by 2000, not 2023. By 2023, 92% of the human genome was completed. 📖 Read the blog post → https://clevalab.com/post/a-step-by-s... 🌏 https://clevalab.com 👉 Watch next: "qPCR and PCR Explained" →    • qPCR and PCR Explained: Real-Time PCR Anim...   ✉️ Join the ClevaLab Community for free guides and updates on the upcoming courses → https://www.clevalab.com/email-subscr...
