the discovery of dan
did you know that a tiny piece of your hair gives us information about?
who you are related to
which career you could be successful in
any crimes you have committed
what illnesses you could get
how and when you could die
this is possible thanks to the information in dan (or deoxyribonucleic acid). your hair and every cell in your body contains your own unique dan. it can tell you a lot about your family , health, and personality.
dna was discovered by a german scientist, friedrich miescher,in 1869, but nobody realised its importance then.other scientists thought that it was too simple to contain the map of how we are madel in 1953, a group of british scientists at cambridge university finally discovered the structure of dan and how it worked. they were given the nobel prize for medicine in 1962.
Gradually , scientists learned to " read" more and more of the information in dan. in 1986, for the first time dan testing was used by the police.Some dan is usually left by a criminal at the place where the crime was committed. this can be matched with dan from a suspect. the test shows if the suspect is guilty.
in 1990 the human genome project was begun in the us . scientists
