What was before DNA fingerprinting?
Before DNA tests, the scientific community used other biological tools to identify people and determine biological relationships. With the introduction of DNA testing in the late 1970s and early 1980s, scientists saw the potential for more powerful tests for identification and determination of biological relationships.
Who is the father of DNA fingerprinting in world?
Professor Sir Alec Jeffreys
How did DNA fingerprinting changed the world?
DNA fingerprinting, one of the great discoveries of the late 20th century, has revolutionized forensic investigations. This review briefly recapitulates 30 years of progress in forensic DNA analysis which helps to convict criminals, exonerate the wrongly accused, and identify victims of crime, disasters, and war.
