Question

Do tears have DNA?

Answer 1

DNA:

1. The molecule found inside cells that carries the genetic material necessary for an organism to develop and function is called DNA.
2. eDNA may occasionally be detected as a symptom of dry eye illness (DED). However, some nucleated cellular components were discovered in human tears, which could be useful in forensic analyses.
3. In actuality, there are three different types of tears: Reflex, emotional, and basal tears.
4. All are produced by the glands that surround the eyes and are essential for the health of the eyes.
5. Due to the presence of nuclease (DNase I), human tears typically lack DNA.
