A2 Biology - DNA profiling (OCR A Chapter 21.1)

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.
