DNA fingerprinting developed by Alec Jeffreys originally used which type of repetitive sequence as a probe?
A{'text': 'Microsatellite repeats', 'label': 'A'}
B{'text': 'LINE retroelements', 'label': 'B'}
C{'text': 'VNTR mini-satellite', 'label': 'C'}
D{'text': 'Telomeric TTAGGG repeats', 'label': 'D'}
Answer & Solution
Correct answer: C. {'text': 'VNTR mini-satellite', 'label': 'C'}
Jeffreys used VNTRs, a class of mini-satellite DNA with highly polymorphic copy numbers, detected by Southern blotting with radiolabelled VNTR probes and autoradiography.
