DNA Profiles & Analysis

DNA Profiles & Analysis

Deoxyribonucleic acid (DNA) profiling is a technique used to scientifically analysis skin cells, hair follicles, blood or saliva. Only a small amount of hair or a few drops of blood provides enough for effective DNA profiling to be successfully carried out.

A persons DNA make up is unique to that individual with the exception of identical twins. Contained in DNA is information which determines our genetic makeup such as physical and biological characteristics. DNA is a collection of molecules called nucleic acids which contain genetic information which when analysed can provide confirmation about a person’s identity, involvement to a crime or determine biological traits. Scientists with DNA experience can differentiate between patterns in the DNA cells, using highly specialised technology samples can be analysed, the structure of the proteins create a genetic code which is very useful in forensic investigations.

The DNA database stores DNA profiles from millions of people, the majority of which have been convicted of crimes or have been suspects. This allows professionals with access to the system to perform a national search to cross reference the profiles and predominantly link or eliminate an individual to an incident. On occasions DNA evidence can lead to convictions many years down the line due to the fact that decades ago DNA wasn’t available or in some cases where no DNA was available.

Crime scenes can have many sources of DNA Essential Forensics will gather all available evidence and transport and store it effectively preserving potentially incriminating evidence.

The presence or absence of DNA cells at a crime scene could mean the difference between a guilty verdict and an acquittal. Essential Forensics are market leaders in DNA profiling and we are confident that we can provide assistance with a positive outcome for any legal case or private investigations where genetic analysis is required.
