Exact time of Death, Seems strange hear this but we can calculate and identify now. On death, the heart of man stopped beating but his genes remain active. The role of these jeans is crucial to know the exact time of death. According to recent research, scientists can know the time of death of a person within 9 minutes on the basis of DNA activity. Changes are up to 24 hours.
There are genetic changes in human tissues for the first 24 hours of death. This shows their activity and with the help of their knowledge, the time of death is revealed.
This information is given by researchers in a report of Nature Communication. Researchers have found RNA survival like DNA after death. RNA is the only chemical cage of DNA but it is disabling. Actually, these are weak and unstable molecules.
Experts say that the molecular process remains only when the enzymes and the chemicals required for it do not end. The researchers analyzed 36 types of human tissues, including brain, skin and lungs. These tissues were collected from more than 500 donors, who died in less than 29 hours.
The gene activity of each tissue is different. Let us know that the Traditional Examples used to predict the timing of death based on body temperature and physical sign. But after the recent research, there can be a lot of help in solving criminal cases in the coming times.
Deoxyribonucleic acid (DNA) is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two bio-polymer strands coiled around each other to form a double helix.
