The Correct Option is D
Solution and Explanation
Concept:
DNA profiling or fingerprinting is a technique used to identify individuals based on their unique genetic code.
• Every individual (except identical twins) has unique repetitive sequences in their DNA.
• These sequences are known as Variable Number Tandem Repeats (VNTRs).
Step 1: Historical Discovery.
In 1984, a British geneticist discovered that certain regions of DNA showed patterns that were unique to individuals. This scientist was Sir Alec Jeffreys (often spelled Alec Jeffery in various examination contexts).
Step 2: Impact of the Discovery.
His work revolutionized forensic science and paternity testing. By using radiolabeled probes to bind to VNTRs, he could produce a visual "barcode" of an individual's DNA. Final Answer: DNA fingerprinting was developed by Alec Jeffery.
