Dr. Alec was the first to develop a new technique for obtaining DNA, which is summarized in several points:
1. The DNA sample is extracted from the body's tissue or fluids, such as hair, blood, or mucus.
2- The sample is separated by a specific enzyme that can cut the DNA strips longitudinally. The bases of adenine A, guanine G in the region, thiamine T and cytosine C are differentiated in another area. Genetic, or genetic scissors.
3 - Arrange these sections using a method called electric discharge, and thus consists of longitudinal lines of the part separated from the tape depends on the length of the number of replicates.
4. The clips are exposed to X-ray-film and printed on it in dark, parallel lines.
Although the DNA molecule is so small (even if all the DNA contained in the Earth's population is over 36 mg), the DNA is relatively large and clear.
Dr. Alec's research did not stop at this technique; he did a study on one of the families in which he inherited the fingerprint. He found that the children were carrying lines half of them came from the mother and the other half from the father, and their simplicity was different from one person to another.
It is enough to test the DNA for a small point of blood; if a single hair falls off the person's body, saliva from the mouth or any of its supplies, this can clearly demonstrate the fingerprint test. "Alec".
The fingerprint may be wiped easily, but the DNA fingerprint is impossible to wipe from behind you, and once the handshake may move your DNA to the hand of the handshake.
If the sample is smaller than required, it will introduce another test, the polymerase polymerase (PCR) reaction, through which we can multiply the amount of DNA in any sample. To another in the human body; they are fixed regardless of the type of fabric; the genetic fingerprint in the eye find similar in the liver .. and heart .. And poetry.
Thus, Dr. Alec Geoffries entered history, and his research has been one of the fastest-growing discoveries in many fields.
