Site-Directed Mutagenesis is a powerful molecular biology technique used to introduce specific changes in the DNA sequence of a gene. It allows researchers to create precise mutations at desired locations in the genome, enabling the study of gene function, protein structure, and various biological processes.

By manipulating the DNA sequence, researchers can investigate the impact of specific mutations on protein function, study disease-causing mutations, and even engineer new proteins with improved properties. This technique has revolutionized the field of molecular biology and has become an indispensable tool for genetic engineering projects.
