Amplicon sequencing is a targeted approach that focuses on specific regions of DNA or RNA within a given sample. It involves amplifying and sequencing a particular gene or genomic region of interest. In the field of microbial ecology, the 16S rRNA gene is commonly targeted for bacteria and archaea. This gene contains conserved regions that allow for the design of universal primers, enabling amplification and sequencing of a wide range of microbial taxa. By sequencing the 16S rRNA gene, researchers can determine the taxonomic composition of the microbial community present in the sample. While amplicon sequencing provides information about the diversity and relative abundance of different taxa, it has limitations in providing functional information. https://www.cd-genomics.com/16s-18s-its-amplicon-sequencing.html
