Metagenomic NGS (mNGS) is simply running all nucleic acids in a sample, which may contain mixed populations of microorganisms, and assigning these to their reference genomes to understand which microbes are present and in what proportions. ... (1) Genomic DNA is extracted and fragmented.

What is the process of metagenomics?

Metagenomics involves obtaining DNA from all microorganisms within a community, without necessarily identifying all of the species involved. After the genes are sequenced and compared with identified sequences, the functions of these genes can be determined.

What are the 3 steps to metagenomics study?
