Assertion (A): “DNA finger printing” has become a powerful tool to establish paternity and identity of criminals in rape and assault cases. Reason (R): Trace evidence such as hairs, saliva and dried semen are adequate for DNA analysis.Codes:
✓ Correct answer: a) Both A and R are true and R is the correct explanation of A.
ExplanationDNA fingerprinting is biotechnique based on analysis of specific regions of DNA that are unique to each individual.This makes it a powerful forensic tool.Assertion (A) is true: DNA fingerprinting, also known as DNA profiling, has become a powerful tool in forensic science for identifying individuals.It is widely used to establish paternity and to identify suspects in criminal cases, including rape and assault.The unique genetic makeup of each individual allows forensic experts to match DNA samples from crime scenes with those of suspects or to determine biological relationships.Reason (R) is true: Trace evidence such as hair, saliva, and dried semen can provide sufficient DNA for analysis.Even small biological samples left at crime scenes can be collected and processed to extract DNA, which can then be compared to known samples to identify individuals.Both Assertion (A) and Reason (R) are true, and Reason (R) correctly explains why DNA fingerprinting is effective in establishing paternity and identifying criminals in rape and assault cases.The ability to analyze DNA from mini
