How is pcr used to identify bacteria

Web7 feb. 2024 · To sequence the 16S rRNA gene, you’d first have to amplify the region by PCR and then sequence the product. However, this provides a small piece of the microbial puzzle. Sequencing all of the DNA in a microbe and assembling these sequences into a genome reveals much more than 16S rRNA gene sequencing can. Web28 mei 2024 · Why do we use PCR to identify bacteria? The method should allow prompt and accurate identification of bacteria . The principle of the method is simple; when a pure PCR product of the 16S gene is obtained, sequenced, and aligned against bacterial DNA data base, then the bacterium can be identified.
