Question

Q. The technique of DNA fingerprinting refers to:

• A. molecular analysis of profiles of DNA samples
• B. analysis of samples using genome sequencing devices
• C. the technique used for molecular analysis of different species
• D. techniques used for identification of fingerprints of individuals

Answer 1

The correct option is A molecular analysis of profiles of DNA samples

Explanation:

DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome through molecular analysis of profiles of DNA samples to produce a pattern unique to an individual. This is called a DNA fingerprint of that person. The probability of having two people with the same DNA fingerprint that are not identical twins is very small. It is a popular laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. Often, DNA samples taken from a crime scene are compared to the DNA sample from a suspect to come to a conclusion.
