Question

DNA fingerprinting technique was first developed by
A. Boysen and Jensen
B. Jeffreys, Wilson, and Thien
C. Schleiden and Schwann
D. Edward and Steptoe

Answer 1

DNA fingerprinting is a technology for determining the unique nucleotide sequences of the DNA. This technique was developed by the British Geneticist, due to which he is considered the Father of DNA fingerprinting.

Complete answer:
DNA fingerprinting is a technique that is used to determine the nucleotide sequence of certain areas that are unique to every person or individual. DNA fingerprinting can distinguish between any two individuals except the monozygotic twins because their $9.9\%$ DNA is the same. This revolutionary technique was developed by Sir Alec John Jeffreys, along with Wilson and Thein. Sir Alec John Jeffreys is a British Geneticist and he is regarded as the Father of DNA fingerprinting due to his contributions to this field. During DNA fingerprinting the DNA is isolated from the sample and then it is hybridized with the VNTR probes. This generates several bands. These bands give a characteristic pattern for any individual. They are then crossed and matched and the results are determined.
Thus, the DNA fingerprinting technique was first developed by Jeffreys, Wilson, and Thien.

Hence, the correct answer is option (B).

Note: DNA fingerprinting is a very important forensic tool. It is used to determine several agendas in forensics that are otherwise impossible. DNA fingerprinting is used in paternal or maternal disputes. It is used for criminal identification in several cases of crimes. It is also used for personal identification of people sometimes. It can also establish close relationships between people and intending immigrants.
