Card 1DNA फिंगरप्रिंटिंग

DNA फिंगरप्रिंटिंग क्या है और यह उपयोगी क्यों है?

Answer

DNA फिंगरप्रिंटिंग एक विधि है जिसका उपयोग पूरी DNA को अनुक्रमित किए बिना विरासत में मिले DNA परिवर्तनों की तुलना करने के लिए किया जाता है। यह व्यक्तियों की पहचान करने, पितृत्व परीक्षण का समर्थन करने औ

Card 2DNA Fingerprinting

What is DNA fingerprinting and why is it useful?

Answer

DNA fingerprinting is a method used to compare inherited DNA variations without sequencing the whole DNA. It helps identify individuals, support paternity testing, and assist forensic and evolutionary

Card 3DNA Fingerprinting

Why can DNA fingerprinting distinguish between individuals when most human DNA is similar?

Answer

About 99.9% of the human genome is the same in all humans, but the remaining 0.1% contains inherited variations. These variations create different DNA patterns in individuals.

Card 4DNA फिंगरप्रिंटिंग

जब अधिकांश मानव DNA समान होते हैं तो DNA फिंगरप्रिंटिंग व्यक्तियों के बीच अंतर क्यों नहीं कर पाती है?

Answer

मानव जीनोम का लगभग ९९.९% भाग सभी मनुष्यों में समान होता है, लेकिन शेष ०.१% में आनुवंशिक भिन्नताएँ होती हैं। ये भिन्नताएँ व्यक्तियों में अलग-अलग DNA पैटर्न बनाती हैं।

Card 5DNA फिंगरप्रिंटिंग

DNA फिंगरप्रिंटिंग में VNTRs क्या है?

Answer

VNTRs चर संख्या के साथ एक साथ दोहराए जाने वाले छोटे DNA अनुक्रम हैं जो एक स्थान पर एक साथ दोहराए जाते हैं। वे व्यक्तियों के बीच अत्यधिक परिवर्तनशील होते हैं और DNA फिंगरप्रिंटिंग का आधार बनाते हैं।

Card 6DNA Fingerprinting

What are VNTRs in DNA fingerprinting?

Answer

VNTRs are variable number tandem repeats, short DNA sequences repeated in tandem at a locus. They are highly variable among individuals and form the basis of DNA fingerprinting.

Card 7DNA Fingerprinting

Differentiate microsatellites and minisatellites.

Answer

Microsatellites are VNTRs with repeated sequences of 1 to 9 bp. Minisatellites are VNTRs with repeated sequences of 10 to 100 bp. Both are used in DNA fingerprinting.

Card 8DNA फिंगरप्रिंटिंग

सूक्ष्म उपग्रहों और लघु उपग्रहों में अंतर बताइए।

Answer

सूक्ष्म उपग्रह VNTRs हैं जिनमें 1 से 9 बीपी के दोहराए गए अनुक्रम हैं। लघु उपग्रह VNTRs हैं जिनमें 10 से 100 बीपी के दोहराए गए अनुक्रम हैं। दोनों का उपयोग DNA फिंगरप्रिंटिंग में किया जाता है।
