The term e-DNA, recently in news, corresponds to which of the following statements?

The e-DNA is associated with the DNA samples collected and recorded in an online portal for future investigations.

The DNA which contains the Epinephrine hormone in excess is known as e-DNA.

The DNA that is present outside the genome spacing is extra and is known as e-DNA.

The airborne DNAs of animals that are shed through their breath, saliva, fur into the environment is called the e-DNA.

Two independent studies have found that the DNA floating in the air can boost biodiversity conservation efforts across the world.

e-DNA Technique

Animals shed DNA through their breath, saliva, fur or faeces into the environment. These DNAs floating in the air.
These airborne DNAs are called environmental DNA (e-DNA).
Tracking animals through e-DNA isn’t a new idea. Biologists have observed aquatic organisms by sequencing e-DNA from water samples.
Similarly, the two teams filtered e-DNA from the air by using sensitive filters attached to vacuum pumps.
After extracting DNA from the air, the teams made copies using polymerase chain reaction (PCR). The last step was DNA sequencing.
They then compared the sequencing results with known sequences to identify the animal.
These e-DNAs can be used to potentially identify and monitor terrestrial animals.
Their findings could help understand the composition of animal communities and detect the spread of non-native species.
But in its current form, the e-DNA technique cannot provide accurate data for population census. But it will in the future.
