Answer :
The collective genes from organisms within a given microbiome is the best definition of the term metagenome.
Metagenomics is the process of establishing a metagenome, which is defined as the recovery and comprehensive sequencing of genetic material directly retrieved from all environmental samples. The advantage of studying the genomes of nonculturable microbes, including viruses, is provided by metagenomics.
In conclusion, a metagenome is a collection of genomes from numerous individuals present in an environment or sample, whereas a genome is the genetic make-up of a single organism.
Researchers can thoroughly sample all of the genes in all of the species present in a given complex sample using shotgun metagenomic sequencing. The technique gives microbiologists the ability to assess bacterial diversity and find out how many germs are present in varied environments.
