Bioinformatics Fundamentals: Finding Hidden Messages in DNA

Modern biology is increasingly becoming a data science. To understand the blueprint of life, we must learn to decode the hidden patterns tucked away in massive DNA sequences using computational logic. This course transitions you from a curious observer to a foundational practitioner of bioinformatics. You will learn to treat DNA as a string of digital information, applying algorithmic thinking to solve biological mysteries without ever needing a physical laboratory. What you'll learn: - Understand the core concepts of DNA replication and the search for genomic origins. - Identify frequent patterns and motifs, known as k-mers, within a genetic sequence. - Apply algorithmic counting and pattern-matching techniques to biological data. - Analyze DNA skew to pinpoint where replication likely starts in bacterial genomes. - Practice working with modern genomic data representations and sequence formats. - Explore how computational tools reveal evolutionary relationships through sequence analysis. The course starts with essential biological terminology and foundational definitions before moving into the logic of pattern discovery. You will read through the step-by-step computational processes used to analyze real-world bacterial DNA. This text-only course is designed for beginners interested in the intersection of biology and computer science, and no prior experience in either field is required.
