What is DNA analysis?

Analysis

DNA is a method of research that has appeared in the age of 80 and is credited to English geneticist Alec Jeffreys. Each species has unique genetic sequences. DNA analysis makes it possible to identify any type of organism by analyzing its genetic sequences. This method can also clarify the identification issues within the species.

Identification within the species may represent more challenges than determining between two different types. For example, it is much easier to determine whether the victim was attacked by a bear or a person than to find out which one has burned. DNA analysis is usually performed by forensic scientists. In cases where individuals need to be identified, forensic scientists tend to use the scanning method of 13 areas of the human genome.

If forensic scientists had only scanned a few areas, DNA analysis would probably not be highly considered accurate. Chances of the same match between two people when 13 regions of the AOPETS are so slim that the results are sometimes called fingerprintsthe fingers of the bottom. Like printing from the index finger, the fingerprints of DNA are generally considered convincing and are usually not subject to great control.

There are several techniques that can be used for DNA analysis. The polymorphism of the length of the restriction fragment (RFLP) was one of the first methods used in forensic research. The polymerase chain reaction (PCR) is a method that allows forensic scientists to amplify a sample and produce millions of copies of DNA from a relatively small sample.

One of the factors that determines the method that the forensic scientist will use is how much its sample is. The whole body is not necessary to perform DNA analysis and there is often no large sample. One hair, tooth, a drop of blood or skin cells usually contain enough unique information about a person to identify it wslepice is used the right technique.

question to be answered is also determined by the methodthat is used for DNA analysis. Every father will hand over his chromosome to his son. Chromosome analysis may therefore be used in situations where the problem is established by paternity.

Because DNA analysis is respected as high -precision, it is used in many parts of the world for many important reasons. Examples include identifying individuals who are suspected of criminals, identifying victims or their remains when identity is not possible by other means, determining the risk of genetic diseases and identifying animals in case of suspected poaching. One can spend your life in prison or be liberated from the punishment of life based on the results of DNA analysis.
