Question

What is DNA fingerprinting? 


  1. molecular analysis of profiles of DNA samples

  2. analysis of DNA samples using imprinting device

  3. techniques used for molecular analysis of different specimens of DNA 

  4. techniques used for identification of fingerprints of individuals 


Solution

The correct option is C

techniques used for molecular analysis of different specimens of DNA 


The arrangement of nucleotides in the DNA of each person differs. The technology of testing the arrangement of nucleotides is called DNA profiling. DNA  profiling is also called as DNA fingerprinting since the arrangement of nucleotides differ from person to person like the difference in the fingerprints of each person. Due to this reason, this technique can be used to identify the culprit in case of murder, robbery etc.

A technique used for manipulating the genes of an organism is called genetic engineering. A technique used for curing diseases through genetic manipulation is called gene therapy.
