DNA Genome Assembly: Overcoming Algorithmic Pitfalls and Repeats

Reassembling a genome from millions of short DNA fragments is one of the most complex puzzles in modern bioinformatics. To build accurate genomic sequences, you must understand how algorithms handle the biological and physical realities of double-stranded DNA. This text-only course guides you through the core computational hurdles of genome assembly, helping you transition from understanding basic DNA structure to analyzing the algorithms designed to resolve repeat sequences and reverse complements. What you'll learn: - Understand the foundational structure of double-stranded DNA and how it translates to computational data. - Identify the algorithmic challenges posed by reverse complements in genomic sequencing reads. - Analyze how repetitive regions in genomes create assembly ambiguity and learn strategies to resolve them. - Explore the differences between overlap-layout-consensus (OLC) and De Bruijn graph assembly approaches. - Examine modern bioinformatics workflows and data formats used to represent genomic sequences. You will start with essential terminology and the biological constraints of double-stranded DNA before diving into algorithmic logic. Through clear written explanations and step-by-step pseudo-code walkthroughs, you will grasp how modern assembly software reconstructs genomes. This course is designed for beginners in bioinformatics, computer science students, or biology enthusiasts with no prior experience in genome assembly.
