Q. Aerial metagenomics’ best refers to which one of the following situations?

Collecting DNA samples from air in a habitat at one go
Understanding the genetic makeup of avian spedes of a habitat
Using air-borne devices collect blood samples from moving animals
Sending drones to inaccessible areas to collect plant and animal samples from land surfaces and water bodies.

Answer: (a) Collecting DNA samples from air in a habitat at one go

“Aermal metagenomics” refers to the collection and analysis of DNA samples from the air or aerosol particles present in a specific habitat.
It involves sampling the air in a particular environment to capture the genetic material (DNA) present in microorganisms, including bacteria, viruses, fungi, and other microscopic organisms.
