How DNA is used to solve crimes

When the DNA matches samples from a crime scene or a DNA databank it virtually guarantees a conviction. DNA can also prove innocence. DNA uses only a small fraction of a person´s genetic code. I have read that the DNA is unique for each and every person so that is why I think it is very efficient for the police to solve crimes by taking the DNA from the suspect and then watching if it matches with the one of the crime. Even though it has been proven that it is not 100% accurate, the DNA is a very precise way for proving innocence for suspects.

The DNA was something that Watson and Circk helped to discover in the 1950. But using it as a way of discovering crimes did not come until 1984.

Only in New York the Cardozo School of Law found that there were more than 100 persons were innocent by DNA so this is crearly making a difference in the way people is judged. They should keep using this method and try to imporve it to make it work at its 100%.

I think they play an important part in science, because they were the ones that helped the understanding of the DNA. Which in my opinion is a really hard work. Not so many people have such intelligence to discover those things and undestand how DNA works and what it does. Both of the stories to me were interesting, I saw that all of these scientists were really prepared and studied a lot in their teenage years, because they went to good colleges. But other people got the credits for her discovery.

Franklin never gave up trying her DNA project, she came very close to solving the DNA structure. The scientists Watson and Crick were the ones who discovered the nucleic acid was made of sugar. They proved that DNA was the one that carried genetic information. They suggested that the DNA could actually be the gene. But they still didn´t know how it worked.

Now the science is much easier because the technollogy we have and that they already made discoveries that were really useful to know better science.
