DNADNA stands for deoxyribonucleic acid.It is a hereditary material found

in humans and almost all other

organisms. It is unique to every person

except identical twinsIt is passed down from

generation to generation, from parents to children, changing

slightly as its passed down.

DNA Profiling DNA profiling is a technique in which a

sample of DNA is tested in a laboratory to

generate information about it. Scientists look specifically for DNA which

can link and identity the source of the sample. It can also be used to compare two samples. DNA profiling can also help police, federal

agents and government officials locate and

identify its origin and whom it belonged to. It also helps people connect with long lost

relatives or family members.

Uses of DNA Profiling Paternity- to find out the biological father of a child. Twins - identical twins share the same genetic material,

while fraternal don to. DNA profiling can identify whether the twins are identical or fraternal.

Siblings - adopted people may want to have DNA tests to make sure that their biological siblings are actually their blood brothers or sisters.

Immigration - some visa applications depend on whether the certain person is related to another. DNA profiling can be used to test whether the two people are related or not.

Criminal justice - DNA testing can help solve crimes by comparing the DNA profiles of suspects to offender samples.

Identification- DNA profiling can be used to identify people that are injured in high risk jobs.

DNA tests can be conducted using samples that would be too small

for other testsThe DNA is in good condition

even after the testsMany cases have been solved due

to the use of matching DNA

from crime scenes

DNA Profiling Used to

Solve Crimes Mark Dixie, who murdered teenage model

Sally Anne Bowman, and Suffolk serial killer Steve Wright were both caught after their DNA was taken for unrelated offences and were afterward linked to the crimes.

DNA profiling was also used to solve the Colette Aram murder case 25 years after the murder was committed by tracing a reckless 19 year old driver’s DNA to his father, who turned out to be the killer.

Hardware & Software Used For DNA Profiling

The specific software that scans people’s fingerprint is called the Automated Fingerprint Identification Systems (AFIS).

The manager director of the LGC (Laboratory of the Government Chemist) Forensics, Dr. Steve Allen, has developed a device in a project known as RapiDNA. This software is said to be able to produce a profile and transmit it to the DNA database and come back with a match all in 60 minutes.
