Analysis and Comparison of DNA

Analysis and Comparison of DNA

The genetic profile we carry is unique to every person and makes everyone different from anybody else.

The genetic baggage we carry is concentrated within the cell inside its nucleus as a nucleic acid called deoxyribonucleic acid – DNA.

The genetic profile is found in the body’s cells of each person and also in the body’s various secretions.

Forensic laboratories examine DNA fragments, which are not encoded, for their properties, and this way, it is possible to both make identifications and to avoid violating a person’s privacy.

The analysis and comparison of DNA makes it possible  to answer, among others, the following questions:

» Is the DNA human, or does it belong to an animal or plant?

» To which living creature does a certain secretion or a certain biological fragment

belong?

» Does the DNA found at a certain location belong to a specific person?

» Does a certain biological sample belong to a specific person?

» Does the DNA found at a certain location contain material from more than one

person?

» What is the gender of the person whose DNA was found (male or female)?

The comparison of DNA is of decisive importance for criminal investigations, matrimonial and family cases as well as in every case a person’s identification is required.

Precisely due to its importance and uniqueness, this important kind of evidence must be handled with special care.
