Development of dna fingerprinting
WebDNA is deoxyribonucleic acid, the molecules in cells that determine the genetic characteristics of all life. It takes the form of a double helix (two strands coiled together). DNA was first discovered in the 19th century by Miescher, from pus on bandages. By the 1940s scientists realised that DNA contained the code for life, and in 1953 Watson ... WebDec 19, 2024 · Read here to learn the significance of DNA fingerprinting. Since the development of fingerprinting a century ago, one of the greatest technological advances in criminal investigation has been DNA analysis. DNA profiling techniques used to analyze biological evidence will undoubtedly link the guilty and eliminate an innocent individual.
