The technique of DNA fingerprinting is based on the principle of
Polymorphism in DNA sequences
DNA fingerprinting is based on the principle of DNA polymorphism, which means variations in DNA sequences among individuals.
Which of the following is a wrong pair?
T=U
✅ Answer: D) T = U
In DNA: A = T, G≡C
In RNA: A = U, G≡C
So T = U is incorrect. Thymine (T) is present in DNA, not RNA.
