(also referred to as environmental and genomics) is the genomic analysis of by direct extraction and cloning of DNA an assemblage of microorganisms. It involves DNA from an environmental sample, cloning DNA into a suitable vector, transforming the clones a host bacterium, and screening the resulting an approach helps in sampling an entire habitat at go. Researchers have shown that environmental (e-DNA) can potentially identify and monitor animals. Animals shed DNA through their saliva, fur or faeces into the environment. These are called e-DNA. Statement A is correct.
