Detailed explanation-1: -DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual. This is a DNA fingerprint. The probability of having two people with the same DNA fingerprint that are not identical twins is very small.

Detailed explanation-2: -DNA fingerprinting is a laboratory technique used to determine the probable identity of a person based on the nucleotide sequences of certain regions of human DNA that are unique to individuals.

Detailed explanation-3: -The researchers found that archived latent prints indeed contained DNA and, using optimized methods, they were able to recover at least a partial DNA profile 90% of the time. One sample even produced a full profile.

Detailed explanation-4: -DNA fingerprinting is a technique that involves isolating and extracting DNA from cells, amplifying it through PCR, and running it through gel electrophoresis. Restriction enzymes are used to cut the DNA into fragments of different sizes that are called short tandem repeats or STRs.

Detailed explanation-5: -In DNA fingerprinting, scientists collect samples of DNA from different sources-for example, from a hair left behind at the crime scene and from the blood of victims and suspects. They then narrow in on the stretches of repetitive DNA scattered throughout these samples.
