Dna fingerprinting: India has used DNA fingerprinting

India has used DNA fingerprinting for establishing guilt in suspects and convicts of court cases. However, the technology can be equally useful in establishing innocence of suspects and convicts. India is yet to have made use of this technology for saving people from wrongful convictions. DNA fingerprinting is a laboratory technique used to determine the probable identity of a person based on the nucleotide sequences of certain regions of human DNA that are unique to individuals. DNA fingerprinting is used in a variety of situations, such as criminal investigations, other forensic purposes and paternity testing. In these situations, one aims to “match” two DNA fingerprints with one another, such as a DNA sample from a known person and one from an unknown person. Learn what DNA fingerprinting is, how it works, and why it is useful for identifying individuals and organisms. Explore the history, techniques, and examples of DNA fingerprinting with this comprehensive guide. What is DNA Fingerprinting ? Satellite DNA 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 DNA fingerprinting . These genes show a high level of polymorphism in all kind of tissues as a result of which they prove to be very useful in forensic studies. Any piece of DNA sample found at a crime scene can be analysed for the ...
