Amplicon sequencing is a molecular biology technique used to analyze specific regions of DNA or RNA. It involves amplifying a target sequence using polymerase chain reaction (PCR) and then sequencing the amplified product. This method is particularly useful for studying genetic variations, identifying pathogens, and monitoring microbial communities.

The process begins with the extraction of DNA or RNA from a sample. Primers, short sequences of DNA or RNA, are designed to bind to the target region of interest. These primers are then used in a PCR reaction to amplify the target sequence. The amplified product, known as an amplicon, is subsequently sequenced using next-generation sequencing (NGS) technologies or traditional Sanger sequencing.

Amplicon sequencing offers several advantages, including high sensitivity and specificity, the ability to analyze multiple samples simultaneously, and the potential for high-throughput analysis. However, it also has limitations, such as the potential for PCR bias and the requirement for prior knowledge of the target sequence.

Applications of amplicon sequencing are diverse and include the identification of genetic mutations, the detection of infectious agents, the analysis of microbial diversity, and the monitoring of environmental samples. This technique has become an essential tool in various fields, including medical diagnostics, epidemiology, and environmental science.
