Site-directed mutagenesis

Site-directed mutagenesis is a precise method used in biology to make specific changes to a DNA sequence. Scientists target a particular spot in a gene and alter its building blocks (nucleotides). This allows them to study how changes affect the gene's function or to develop proteins with new properties. The process involves copying the DNA, introducing the desired mutation, and then using the modified DNA to create proteins or cells with specific characteristics. It’s a powerful tool for research, medical applications, and developing new therapies.
