  1. 1. DNA & forensic science By: Sabine Boellert
  2. 2. What does DNA means any ways? <ul><li>Imagine your body is a computer. It needs lots of bits to make it work, but most importantly it needs a computer programme. </li></ul><ul><li>The computer programme can only work with code, which helps make the computer work. </li></ul><ul><li>DNA (which stands for Deoxyribonucleic acid) is like the computer programme, except it is found in all living things. </li></ul><ul><li>DNA contains the instructions for a living thing to grow and to work. These instructions are like the code in a computer programme, and in living things are called genes. </li></ul>
  3. 3. The components of DNA <ul><li>The main components of DNA are: </li></ul><ul><li>Purine </li></ul><ul><li>Adenine </li></ul><ul><li>Guanine </li></ul><ul><li>Pyrimidine </li></ul>
  4. 4. In what way can DNA and forensic science help us? <ul><li>In fact it can help us a lot because it help us recognize the person that commit a crime or that is dead just by a simple blood test they can figure out who are you because in to your record they have your blood type and stuff like your saliva (DNA). </li></ul>
  5. 5. And how can it affect us? <ul><li>If you happen to be a robber or a killer than you are most probably not really going to like this because DNA helps investigators to define who did the crime, by your finger print the FBI can get to know who you are so next time you are thinking about killing or robbing someone or something make sure you use glovs or something so they don't fiang out who you are!! </li></ul>
  6. 6. How does DNA work? <ul><li>DNA work by little particles called: molecule that make a thing call DNA that is like your identification Only one-tenth of a single percent of DNA (about 3 million bases) if you confider a little particle of DNA as the whole is like 1 % of it can change dramatically the way you look )differs from one person to the next. The are for scientist can make you DNA profile. By using samples from blood, bone, hair, and other body and others…. </li></ul>
  7. 7. How can you identify it? <ul><li>DNA identification can be really useful if you used intelligently. also, portions must be large enough to overcome the fact that human mating is not absolutely random it means by that is that only one little particle in the DNA can change your aspects significantly </li></ul>
  8. 8. What can we use DNA for? <ul><li>Identify people that cause a crime and mach them with the DNA left in the spot and theirs </li></ul><ul><li>Protect innocent people </li></ul><ul><li>Identify crime and their victims </li></ul><ul><li>Identify paternity and other family relationships </li></ul><ul><li>To protect in danger animals </li></ul><ul><li>identify dangerous infections or pollution </li></ul><ul><li>Mach organs with compatible revisers </li></ul><ul><li>Make sure that some food are good quality such as caviar and wine </li></ul>
  9. 9. A couple of the most known branches of investigation the FBI and the CIA <ul><li>They are both from the USA they both fight for the safety in the USA and investigate the crime that occur </li></ul><ul><li>CAI stand for Central Intelligence Agency. </li></ul><ul><li>FBI stands for Federal Bureau of Investigation. </li></ul>
  10. 10. Now a little quiz about my power point!!! <ul><li>What can it help us for? </li></ul><ul><li>What can they tell by it? </li></ul><ul><li>What are the most known investigation branches in the usa? </li></ul><ul><li>how can you define who is one of your family member? </li></ul>
  11. 11. Resources: <ul><li> </li></ul><ul><li> </li></ul><ul><li> </li></ul><ul><li> </li></ul>
