Metagenomics

Definition

Metagenomics is the study of genetic material recovered directly from environmental samples. It enables the analysis of microbial communities without the need for culturing.

5 Must Know Facts For Your Next Test

1. Metagenomics allows for the identification and characterization of microbes in diverse environments.
2. It uses high-throughput sequencing technologies to analyze DNA from mixed microbial populations.
3. Metagenomic data can reveal functional genes and metabolic pathways present in microbial communities.
4. One application is discovering new natural products, such as antibiotics, from unculturable microorganisms.
5. Bioinformatics tools are essential for assembling and interpreting metagenomic sequences.
