DNA fingerprinting, also known as genetic profiling, is 39 years old as of 2024.
The Development of DNA Fingerprinting
Sir Alec Jeffreys and his team originally developed the process. However, the initial method was not suitable for forensic applications. As noted in the provided reference, "Genetic profiling as a forensic tool," a variation of the original technique, known as "genetic profiling," was created in 1985 specifically for forensic use.
Key Milestones
- Initial Method: Before 1985, an initial technique existed that was not practical for forensic use.
- 1985 - Genetic Profiling: Sir Alec Jeffreys and his team developed a modified method suitable for forensic science in 1985. This was a significant advancement, making it a crucial tool.
Forensic Use
Genetic profiling's first application caught public attention, highlighting the technique's power and potential.
Calculation
To calculate the age, we subtract the year of its development for forensic use (1985) from the current year (2024):
- 2024 - 1985 = 39 years
Therefore, DNA fingerprinting, or genetic profiling as used in forensics, is 39 years old.
