This is because they have an extremely sensitive nose that can detect even the faintest odour of the human body.
Do tears have DNA?
Human tears do not have the ability to cleave DNA due to the presence of nuclease. However, in the absence of DNase, the DNA can be cleaved by a variety of enzymes, including DNA polymerase II (DPII) and DNA glycosylase (Glyceraldehyde-3-phosphate dehydrogenase [GAPDH]). In the present study, we investigated the effect of aqueous and nonaqueous solutions on the cleavage of human DNA by DpII and GAPDHA.
We found that the concentration of the solution (0.5 mM) was sufficient to induce DNA fragmentation in a concentration-dependent manner. In contrast, a solution of 0.1 mM was insufficient to cause DNA damage. These results suggest that a pH of 6.0 or higher is required for the formation of DNA adducts.
