DNA profiling is the technique of finding the difference between the satellite DNA regions in the genome. These regions are stretches of repetitive DNA which do not code for any specific protein. These non-coding sequences form a major chunk of the DNA profile of humans. They depict a high level of polymorphism and are the basis of … Read more
