Nucleic acid amplification is a laboratory technique used to increase the quantity of specific DNA or RNA sequences. This process allows scientists to create millions of copies of a target nucleic acid, making it easier to study and analyze. Common methods include Polymerase Chain Reaction (PCR) and LAMP (Loop-mediated Isothermal Amplification). These techniques are essential in various fields, including medical diagnostics, forensic science, and genetic research. By amplifying nucleic acids, researchers can detect pathogens, identify genetic mutations, and conduct various analyses that require precise genetic information.
