Site-directed mutagenesis is a laboratory method that allows researchers to deliberately change the DNA sequence at a specific location. Unlike random mutations, SDM enables precise genetic modifications using genetic engineering techniques. It is widely used in: Molecular biology Genetic research Protein engineering 🎯 Why is it Important? SDM helps researchers: Study gene regulation Analyze the relationship between protein structure and function Understand the functional and structural roles of specific amino acid residues By comparing: 🧬 Mutant protein (with amino acid change) 🧬 Wild-type protein (normal form) Scientists can determine how specific changes affect protein activity and biological function. 🔄 Conventional (Random) Mutagenesis vs Site-Directed Mutagenesis Conventional Mutagenesis Random process Mutations occur at unspecified DNA positions Requires screening of many organisms to find desired mutation Site-Directed Mutagenesis Targeted and specific Constructed using genetic engineering Does not require extensive screening 🧪 Types of In Vitro Site-Directed Mutagenesis Methods 1️⃣ Non-PCR-Based Methods Cassette Mutagenesis Design of Mutagenic Oligonucleotides Primer Extension Mutagenesis 2️⃣ PCR-Based Methods More frequently used Faster and more efficient High accuracy
