In forensic analysis, fingernail material can serve as an important source of DNA. 1, 2 Because of the special composition and structure of fingernails that embody DNA in keratinized cells, DNA extraction procedures are more complex than usual protocols applied for fresh somatic cells.

['The sample of DNA can easily be ruined during the process of DNA fingerprinting, causing the sample to become completely useless for testing.', 'The process itself is complex and tedious, and can give results that may be hard to interpret.']

Because DNA is unique to an individual, we can use DNA fingerprinting to match genetic information with the person it came from. The restriction fragment length polymorphism technique (RFLP) "cuts" out genes which are likely to be differentiating factors using restriction enzymes.

Like hair testing, nail testing can be used to detect drug and alcohol use across long detection windows of between two weeks and eight months – a figure which varies according to whether the sample is a fingernail or toenail.

They shouldn't damage your natural nails if you are careful. Most of the damage, if any, could occur if you are too rough in the removal process.

Most of us do know that nails are made of a tough, dead substance called keratin, the same material that makes up hair. But nails actually start out as living cells. Behind the cuticles on fingers and toes, just beneath the skin, a structure called the "root" churns out living cells that go on to form the nail.

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.

A) 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.

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect.

Well first of all any hair you donate to Locks of Love wouldn't contain DNA because your hair alone contains no DNA. The DNA retrievable from hair would be from a skin tag usually found when a hair is forcibly removed from the source not when it is cut.

The main difference between a round nail and the clipped nail is that the head of the clipped nail has a small portion of the head clipped to form a D shape. This allows the clipped nails to be arranged very close to each other in a power nailer.
