All that is required to assign a gene fingerprint is a small sample of tissue that can extract DNA from the ribosome DNA. For example:
* A sample of blood in the case of proof of paternity.
* Specimen of sperm in case of rape.
* A piece of skin under the nails or bristles of the body rooted in the case of death after resisting the aggressor.
* Frozen or dry sperm or blood at the scene of the crime.
* Sample saliva.
In 1997, Roland Van and Maxwell Jones isolated the genetic material from objects that were touched, such as keys, telephone and cups. After extracting the genetic material, they were cut by the restriction enzymes, then separated by Electrophoresis and transferred to a nylon membrane, Then using a special pathway .. Probes The gene fingerprint is set on a ray film.
