The DNA of a person is responsible for providing information regarding who and what the person is since it contains the design of the genetically passed traits taken from both parents. A lot of information may be attained when one carefully studies the DNA and relates it to possible other discoveries about the person, such as parentage, disease predisposition, etc. DNA is responsible for the person's hair color, eye color, build, susceptibility to certain disorders, and a lot more. Careful analysis must be done in order to use the DNA as a means to study and evaluate a person with regard to inherent traits passed on by his/her parents.

DNA analysis entails the careful scrutiny of the DNA. Understanding how the DNA works, its physical structure, the limits of its characteristics, and how these all help in providing much needed personal information are some of the ways in which DNA properties are optimized. Not everyone can successfully and properly analyze DNA. Aside from years of study devoted to the understanding of DNA, DNA analysts also go through years of experience and practice in laboratories and in the practice of DNA testing and analysis to enable them to analyze DNA and how it works. Training of DNA analysts also includes understanding sophisticated tools and machines designed for specific DNA analysis. Proper management and use of these devices would make them more efficient in the effort to analyze DNA correctly.

Most DNA consists of 23 pairs of chromosomes, the mitochondrial DNA inherited from the mother, and red blood cells. All these elements are carefully purified, studied, and then measured against existing DNA criteria, depending on which use the DNA analysis is deemed for. DNA analysis determines the sequence of the base pairs along the length of the DNA and will provide information as to which of the gene components contains just genes, which regulate genes, which among them have functions, or which have functions still to be discovered.

Several commonly used DNA analysis techniques include: digestion by restriction endonucleases, gel electrophoresis, blotting and hybridization, synthesis of nucleic acids through polymerase, synthesis of nucleic acid probes, nucleotide sequencing, molecular cloning, or the analysis of reporter genes.
