HOW DNA IS USED IN CRIMINAL INVESTIGATIONS

DNA has revolutionized the way of criminal justice systemthat investigates crimes. When suspects DNA matches samples from a crime scene or a DNA databank it virtually guarantees a conviction. With the DNA that matches the suspects it is 100% that he or she is guilty of the murder. The hystory of DNA in criminal investigations reveals a profile unmatched by any other forensic technology. Like for example in the JonBenet Ramsey case, the suspects where 3, the mom, the dad, and  his brother Bruce.

JonBenet Rasmery was known as the “Beauty Queen with Heavy Make Up”. She was born in Atlanta, Georgia, on August 6, 1990. When she was nine months old, the family relocated to Boulder, Colorado. Her first name was a portmanteau of her father’s first and middle names, John Bennett; her middle name was the first name of her mother, the late Patricia “Patsy” Ramsey. JonBenét was enrolled by her mother in a variety of different beauty pageants in several states. Patricia Ramsey funded some of the contests that JonBenét participated in, as well as rock climbing and violin lessons. Her active role in pageants was highly scrutinized by media following the murder.From the day in 1996 when JonBenet was found dead in the basement of her home in Boulder, Colorado, the Boulder police and a large proportion of the world’s media believed that her parents, John and Patsy Ramsey, were responsible for her death.

Suspect number one is Bruce (JonBenet brother), because in the DNA they only find out it was a white male with blonde hair. The dad is broen hair and it is a male so the court continues in sesion since December 24, 1996. The mom died in 2006 because of a cancer in the ovar, the sad thing is that she died  not knowing who was the killer of her beautyfull daughter.

PIONEER MOLECULAR BIOLOGIST (Rosalind Elsie Franklin)

Born at London, England, July 25,1920.

She worked as a scientist and she discovered the structure of the DNA. Because she was a woman she wasn´t recognized or that fameous as she should be. She was one of the few girls who attended school in London that taught physics and chemistry. She decided to become a scientist at age 15 but her dad didn´t suport her because it was really weird to see a scientis girl, at that time most scientist were men. Her father was against her to become a scientist so he wanted her to be a social worker.

In 1938 she went to Newnham College, Campbridge, graduated in 1941. She wanted to graduate as fellowship but she quited in 1942, she worked at the British Coal Utilization Research Association, where she studied fundamental studies of carbon and graphite microstuctures. After Cambridge se spent three years in Paris at the Laboratoire Central des Services Chimiques de L´Etat, where she learned X-ray diffraction techniques.

She dicovered the structure of the DNA and she was never recognized as the woman who descovered the structure od DNA. Instead other scientist where recognized with the big workt scientis Rosalind Elsie Frankling discovered. They won prizes but she didn´t.

She died at London, England, April 16,1958.
