How is DNA preserved in cremated remains? ... The actual ashes are thus useless as they will not contain DNA. It is the bones and teeth that could potentially hold some DNA viable for analysis. However, after the cremation, the bones and teeth left behind are turned into a find powder (a process known as pulverization).

It's now possible to actually write DNA, which could bring an iconic Ice Age herbivore back to life. Jurassic Park imagined a future in which it was possible to bring dinosaurs back to life. Now, that fiction may become reality as geneticists seek to resurrect the woolly mammoth.

According to FamilyTreeDNA, the F.B.I. will have access to its website like any other user: After uploading a person's DNA file, investigators can search for potential relatives with overlapping DNA. Detectives will have access to the same repository of genealogical records as all users, the company said.

After cremation, the remaining metal is removed and the remains are ground. The “ashes” are transferred to either a temporary container or in an urn provided by the family.

DNA collection and analysis is an integral part of CSI, and the samples obtained are often extremely low in concentration and low quality. Thus, PCR is routinely used to amplify this DNA to amounts that can be analyzed further by methods such as fingerprinting, sequencing, etc. to identify people involved in the crime.

Possible Dinosaur DNA Has Been Found. The tiny fossil is unassuming, as dinosaur remains go. ... This speed would mean paleontologists can only hope to recover recognizable DNA sequences from creatures that lived and died within the past 6.8 million years—far short of even the last nonavian dinosaurs.

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA.

Teeth and bones are frequently the only sources of DNA available for identification of degraded or fragmented human remains. The unique composition of teeth and their location in the jawbone provide additional protection to DNA compared to bones making them a preferred source of DNA in many cases.

It is essential to isolate high-quality DNA from muscle tissue for PCR-based applications in traceability of animal origin. ... Deoxyribonucleic acid quantity was significantly reduced in cooked meat samples compared with raw (6.5 vs. 56.6 ng/microL; P < 0.001), but there was no relationship with cooking temperature.

To turn your ashes into a tree or to plant a tree with your ashes simply pace the ashes in a tree pod such as The Living Urn, add the additives and then plant the bio urn combination with the young tree. As a result, the ashes will turn into a tree in a symbolic way.

Still, the technology has limitations. Most genetic tests take 24-72 hours but the time taken for DNA to go from crime scene to identification can span as long as 14 days. By the time that the results are back, the suspects often have been released.

If intact DNA is present in these dinosaur fossils, scientists may need to reappraise the molecule's ruggedness. Past studies have found that genetic material disintegrates in bones after a few million years. ... The preserved dinosaur cells were probably embedded in cartilage, Schweitzer says, which lacks pores.

Cremation ashes may be harmful when placed in the soil or around trees or plants. While cremains are composed of nutrients that plants require, primarily calcium, potassium and phosphorus, human ashes also contain an extremely high amount of salt, which is toxic for most plants and can be leached into the soil.

Mitochondrial DNA is maternally inherited. The high sensitivity of mtDNA analysis allows forensic scientists to obtain information from old items of evidence associated with cold cases and small pieces of evidence containing little biological material.

The hair follicle at the base of human hairs contains cellular material rich in DNA. In order to be used for DNA analysis, the hair must have been pulled from the body -- hairs that have been broken off do not contain DNA. ... Most healthy individuals, however, do not excrete epithelial cells in their urine.
