dna fingerprinting | dna profiling/dna typing | dna फिंगरप्रिंटिंग/प्रोफाइलिंग का सिद्धान्त, उपयोग

डीएनए फिंगरप्रिंटिंग (DNA FINGERPRINTING)
जिस प्रकार पहले व्यक्तियों की पहचान के लिए परम्परागत रूप से अंगुली के चिन्ह प्रयुक्त किये जाते हैं, इसी प्रकार से अब इसका स्थान डीएनए फिंगरप्रिंटिंग ने ले लिया है। अलग-अलग मानव के DNA के न्यूक्लिओटाइड्स क्रम की तुलना करके उनके बीच सम्बन्ध के अध्ययन की प्रक्रिया को डीएनए फिंगरप्रिंटिंग (DNA Finger Printing) कहते हैं। इस विधि की खोज ऐलेक्स जेफ्री (Alex Jeffery) व उनके सहयोगियों ने 1985 में की। इसे अब व्यापक कानूनी स्वीकृति प्राप्त हो गई है। इस विधि का अधिकाधिक उपयोग प्राणियों के सम्बन्धों को निश्चित करने के लिए तथा अनेक अपराधों (हत्या, बलात्कार आदि) की जाँच में किया जाता है।
DNA फिंगरप्रिंटिंग का सिद्धान्त (Principle of DNA Fingerprinting) और dna प्रोफाइलिंग के उपयोग (Applications of DNA Profiling) भी बताए हैं।
