About Environmental DNA
● It consists of the genetic material, such as DNA from cells, tissues, fluids, and waste, that organisms leave behind in their surroundings (e.g., water, soil, air, etc.).
● Application: Used for mapping the presence and distribution of species, monitoring ecosystems, and more.
● Significance: It is non-invasive, highly sensitive, and offers a rapid and cost-effective alternative to other biomonitoring techniques.
