Question

DNA fingerprinting refers to the process which

• A. identifies differences in some specific regions in DNA sequence
• B. identifies the patterns of fingerprints
• C. identifies the marks on an individual body due to genetic mutation
• D. All of the above
  

Answer 1

The correct option is A identifies differences in some specific regions in DNA sequence

DNA fingerprinting, devised by Alec Jeffery helps to identify the patterns of genetic material that are present in an individual specifically. In humans, 99% of the DNA is the same, the difference is only 0.1% which makes all the difference. These 0.1% differences are because of repetitive DNA which varies from chromosome to chromosome in an individual. In DNA fingerprinting these repetitive patterns are targeted to find the individual’s genetic patterns.
