WebSimple creatures like bacteria have just one long, circular piece of DNA made up of two intertwined DNA strands. The human genome, the set of DNA in people, has many more strands of DNA. Most of humans’ DNA is typically packaged into 46 chromosomes located in the cell’s nucleus, which is a specialized compartment for storing DNA. WebWhat is 16s rDNA and how is it used to identify species of bacteria? 16s rDNA is a piece of DNA used for identifying bacteria the region codes for a small subunit of ribosomal RNA. Identification relies on matching the sequence form your sample against a database of all known 16s rDNA sequences
