What Is DNA?
DNA is Deoxyribonucleic Acid and is the genetic material that is found in the nucleus in most cells in the human body (nuclear DNA). DNA is also found in the energy-producing mitochondria of a cell (mitochondrial DNA). Nuclear DNA is inherited in equal portions from a person’s mother and father. Therefore, each person shares 50% of their DNA with their mother and 50% with their father. Full biological siblings also share DNA with each other. To a lesser degree, individuals also share DNA with other relatives such as aunts, uncles, cousins, etc. Mitochondrial DNA is inherited maternally. Therefore, every child (male or female) of a particular woman has an exact copy of his/her mother’s mitochondrial DNA. DNA on the Y-chromosome (present in males only) is inherited paternally. Therefore, all males who share the same paternal lineage would be expected to have the same Y-DNA profile.
Deoxyribonucleic Acid, located inside our cells, carries our genetic information from one generation to the next. This information is necessary for the inheritance of our unique characteristics. How accurate is DNA paternity testing? A DNA Paternity testing is the most accurate way to determine the paternity of an individual. When the DNA patterns of the tested parties are analyzed, the child and alleged father must have at least one allele in common. We guarantee a paternity probability of 99.9% or higher for every test. If there are at least three (3) non-matches between the child and the tested man, then it is concluded with 100% accuracy that he is not the biological father. What should I look for in a DNA testing company? The DNA testing process is extremely important and can seem very overwhelming. It is essential that the company you choose be highly qualified and experienced. The laboratory should also be equipped with the most recent and reliable technology. In addition, the c
DNA, or deoxyribonucleic acid, is the fundamental building block for an individual’s entire genetic makeup. It is a component of virtually every cell in the human body. Further, a person’s DNA is the same in every cell. For example, the DNA in a man’s blood is the same as the DNA in his skin cells, semen, and saliva. DNA is a powerful tool because each person’s DNA is different from every other individual’s, except for identical twins. Because of that difference, DNA collected from a crime scene can either link a suspect to the evidence or eliminate a suspect, similar to the use of fingerprints. It also can identify a victim through DNA from relatives, even when no body can be found. And when evidence from one crime scene is compared with evidence from another, those crime scenes can be linked to the same perpetrator locally, statewide, and across the Nation. Forensically valuable DNA can be found on evidence that is decades old. However, several factors can affect the DNA left at a cr
