State
Metagenomics studies the collective genomes of multiple species growing together in an environmental niche, without first isolating each species in pure culture.
Show
Sequencing DNA extracted directly from a soil sample identifies species present in that community that pure-culture methods would miss.
Watch for
Metagenomics studies a community's combined genetic material directly — it does not require isolating and culturing each member species first.
