Question
Chapter 19.8, Problem 1MQ
Summary Introduction
The molecular study of microbial communities is known as environmental genomics or metagenomics. Metagenomics is used to study all genes (functional capacity) in the microbial community. Metatranscriptomics and metaproteomics target RNAs (gene expression) and proteins in the microbial community, respectively.
