DNA Forensic has been an emerging field that
which technology is constantly advancing. Forensic DNA can be
used to not only identify people, but to also solve crimes.
Our staff works hard to make the DNA Identity Testing Center your choice of provider for all DNA testing services. We ensure superior quality, service and convenience to our clients. In our commitment to providing convenience, please know that we provide a free DNASwabTM Home DNA Collection Kit for use in all types of private DNA tests.

DNA
(Deoxyribonucleic Acid)
DNA is found in the nucleus of all cells and is
the blueprint for an organism. No blueprint is the
same, and it cannot be altered either. This
steadfast consistency has been essential in the
field of DNA Forensics to help with solving crime.
DNA can be extraction from number types of
samples, such as hair roots, saliva, clothing,
semen, blood teeth, fingernails and much more. |

Mitochondrial DNA
Mitochondrial are structures inside the cell and
their essential function is to convert food into
energy. These mitochondria have their own DNA
molecules (mtDNA) which can create a DNA profile.
This DNA, which is only inherited through the
mother, can often be easier to locate and extract
than nuclear DNA. It is useful for DNA Forensics
when identifying victims of mass disasters, in the
cases that nuclear DNA could be damaged. |

Advances in DNA Technology
Not only can DNA link a person to a crime, it can
also link a person to several crimes in different
locations. Once the DNA is entered in CODIS
(Combined DNA Index System), the software can
identify matching markers from the DNA found from
various crime scenes in the system to the suspects
DNA. |

PCR Analysis
Polymerase chain reaction (PCR) is used to make
millions of exact copies of DNA from a biological
sample. DNA amplification with PCR allows DNA
analysis on biological samples as small as a few
skin cells. With RFLP, DNA samples would have to
be about the size of a quarter. The ability of PCR
to amplify such tiny quantities of DNA enables
even highly degraded samples to be analyzed. Great
care, however, must be taken to prevent
contamination with other biological materials
during the identifying, collecting, and preserving
of a sample. |
