Metataxonomic and metagenomic approaches vs. culture-based techniques Bethesda, MD 20894, Web Policies Metagenomics is not the same as Metataxonomics [ 5, 20 ], since it uses whole-metagenome sequencing (WMS) to investigate the complete genome of the microbiota, while Metataxonomics uses next generation sequencing (NGS) to obtain the gene sequence of the 16S ribosomal ribonucleic acid (rRNA), which appears in all bacteria [ 21 ]. This not only can assign taxonomy and quantify the organisms down to the species level, but it can also assign function as it will sequence many different parts of each organism's genome. FOIA In contrast, metataxonomics utilises only 16S rRNA analysis. Careers. Metagenomics vs Genomics - Difference Between Metagenomics produces a taxonomical profile of the sample, metatranscriptomics helps us to obtain a functional profile, and metabolomics completes the picture by determining which byproducts are being released into the environment.
