Read the following statements regarding DNA fingerprinting and VNTRs: A. Digestion of DNA is carried out by restriction endonucleases. B. VNTR belongs to a class of satellite DNA referred to as mini-satellite. C. Separation of DNA fragments is achieved by polymerase chain reaction (PCR). D. The sensitivity of the DNA fingerprinting technique has been increased by the use of PCR. E. The autoradiogram gives identical b

Step-by-step solution

Statement A is correct: In DNA fingerprinting, the isolated DNA is digested by restriction endonucleases. Statement B is correct: Variable Number of Tandem Repeats (VNTR) belongs to a class of satellite DNA known as mini-satellite. Statement C is incorrect: Separation of DNA fragments is done by gel electrophoresis, not by PCR. PCR is a technique used for the amplification of DNA. Statement D is correct: The sensitivity of the technique has been increased by the use of PCR, allowing analysis to be performed even fr
