Question

how has biotechnology impacted forensic science?

Explanation:

Biotechnology has revolutionized forensic science. DNA profiling, a key biotech tool, allows for highly accurate identification of individuals. It can extract DNA from minute samples like hair, saliva, or blood stains. This has led to solving cold cases, exonerating the wrongly convicted, and improving criminal investigations. Biotech also aids in analyzing pathogens (e.g., in bioterrorism cases) and in species identification (e.g., in wildlife crime).

Answer:

Biotechnology has had a profound impact on forensic science. DNA profiling, a major biotech advancement, enables precise individual identification using tiny biological samples (e.g., hair, saliva, blood). This has been crucial in solving old cases, freeing the wrongly accused, and enhancing criminal probes. Additionally, biotech helps in pathogen analysis (for bioterrorism) and species identification (for wildlife crimes).
