Question

How long does DNA in urine last?

Answer 1

DNA in urine

1. Urine does not have DNA wholly present.
2. Instead, it contains epithelial cells that have DNA.
3. If it is stored at 20 ° C for twenty-eight days, about seventy-five percent of the DNA is destroyed.
4. A temperature of 80 ° C improves recovery after up to twenty-eight days of storage.
5. Therefore, urine contains DNA that lasts for 28 days.
