Site-Directed Mutagenesis

Site-directed mutagenesis is a molecular biology technique used to make precise modifications to a gene or DNA sequence. It allows specific changes to be made to a strand of DNA in order to study the function and consequences of the mutation, or to produce protein variants with specific properties. Site-directed mutagenesis is most commonly used in the study of protein-coding genes to study gene regulation, protein structure and function, and as a tool in biotechnology and medicine. It is a valuable tool for researchers in the fields of genetics, biochemistry, and molecular biology.
