Leicester University geneticist Alec Jeffreys developed a technique called DNA fingerprinting in 1985. It allows DNA samples from different people to be compared to look for similarities and differences. It is useful for solving crimes and can also confirm if people are related to each other, like in paternity testing. Any two people in the world have 99.9% of their DNA the same, so this process analyses the differences in the remaining 0.1%. This modern technology is called DNA profiling.
Paul Andersen describes the process of DNA fingerprinting and DNA profiling. He explains how variability in STRs can be used to identify individuals. He explains the importance of DNA fingerprinting in forensics and paternity cases.
DNA profiling is a technique where we can use to identify an individual based on their unique DNA. People all have different number of repeats in their satellite DNA, so therefore can generate a different DNA profile. It is commonly used in forensics and paternity testing, where we compare several individuals' DNA profile to identify the person we are looking for. In this video I will explain the principles behind DNA profiling and the detailed process of it
In this episode of Keipert Labs, we delve into how DNA profiling (also known as DNA fingerprinting) works. We''ll discuss coding and non-coding regions of the DNA strand and polymorphisms, the highly variable regions that are most interesting to the forensic scientist.
