Intro
The technique of DNA profiling was first discovered in 1985 by Sir Alec Jefferys, a Leicester University geneticist. The work that he did in the laboratory led to the discovery of the technique for genetic profiling, which revealed a pioneer method of biological identification. A humans DNA can be found in hair, saliva, blood, and other various human properties. Sir Alec Jeffreys knew that what he had done was going to be revolutionary. After his discovery, he said “My life changed on Monday morning at 9:05 am, September 10th, 1984. What emerged what the world’s first genetic fingerprint” (3). Since it was first discovered in 1985, DNA profiling has had a significant impact on society and has changed forensic science for the better by expanding the amount of information we are capable of obtaining, making it a turning point in history.
Scientific Foundation of DNA Profiling
The DNA (also known as Deoxyribonucleic acid) in cells is formed of two long strands that wrap around each other. There are four different types of bases in DNA, A (adenine), C (cytosine), G (guanine), T (thymine). These bases join together, A with T and U with G, to form a structure that looks like the twisted steps of a …show more content…
Some people think DNA profiling is great, while others think it is unnecessary. There are pros and cons to DNA profiling. The first pro is that it is not invasive. Getting a sample of DNA is as simple as swabbing a cheek with a sterile cotton swab. Also, DNA profiling reduces the amount of wrongful conditions that occur. No evidence is more concrete than DNA. Additionally, DNA profiling eliminates the possibility of manipulation in paternity tests. Previously, paternity tests were based off of verbal and situational evidence about who the child should be with. No one is capable of manipulating their own DNA to better their chances of winning a paternity case. DNA profiles are very solid
