The first known use of fingerprinting was in 9th century China, where merchants applied their fingerprints to documents authenticating a record of debt. It was not until the end of the 19th century that was adopted by investigators of crime.

DNA fingerprinting emerged on the scene in the mid-1980s, with the first practical method developed by Sir Alec Jeffreys in 1984. It revolutionized forensic science and paternity testing by providing a unique genetic profile for each individual.
Well actual fingerprinting started in Persia in the 1400's but forensic finger printing started in the 1800's like to keep records or to find your print at a crime seane
Yes, DNA fingerprinting is commonly used in forensic investigations to identify or exclude suspects in criminal cases. This technique analyzes unique patterns in an individual's DNA, which can be compared to DNA collected at a crime scene to determine a match.
Yes, DNA fingerprinting is a powerful tool for solving crimes because it can definitively link a suspect to a crime scene or victim. DNA evidence is scientifically reliable and has high accuracy, which can help prosecutors secure convictions or help exonerate innocent suspects. However, it is important to consider the chain of custody and proper handling of DNA samples to ensure the integrity of the evidence.
a process called DNA profiling, in which a sample is collected from a crime scene and compared to a suspect's DNA to determine if there is a match. This method is highly accurate and is commonly used in criminal investigations to establish a link between a suspect and a crime scene.

Yes, coding DNA can be used for DNA fingerprinting. Coding DNA, which contains genes that encode for proteins, can contain genetic variations that are unique to each individual. These variations can be used as markers in DNA fingerprinting to identify individuals or determine relationships between individuals.
