. The basis of DNA fingerprinting is
A: The double helix
B: Error in base sequence
C: Polymorphism in sequence
D: DNA replication
E: DNA coiling
DNA Fingerprinting is used to compare the DNA from different sources.
It includes identification of differences in the specific sequences of DNA called Repetitive DNA.
It is based on the minor sequence differences between individuals.
These variations are Restriction fragment Length Polymorphisms (RFLP). Southern blotting is used to detect them.
Option C is correct.
