Mention the application DNA finger printing techniqe
Answers
Explanation:
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.
Seven steps to understanding DNA fingerprinting:
Extracting the DNA from cells.
Cutting up the DNA using an enzyme.
Separating the DNA fragments on a gel.
Transferring the DNA onto paper.
Adding the radioactive probe.
Setting up the X-ray film.

DNA fingerprinting. Image caption: 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.
Answer:
DNA fingerprinting is a technique used to identify and analyze the variations in various individuals at the level of DNA. It is based on variability and polymorphism in DNA sequences. (1) It is used in forensic science to identify potential crime suspects. (2) It is used to establish paternity and family relationships.
Explanation:
crime scene can contain biological samples, including blood, semen, saliva, skin, urine and hair, from perpetrators, victims and bystanders that can be processed to provide DNA fingerprints. The DNA fingerprints obtained are used to search existing databases for matches and to identify victims or suspects.DNA fingerprinting: Applications. ... The techniques used in DNA fingerprinting also have applications in paleontology, archaeology, various fields of biology, and medical diagnostics. It has, for example, been used to match the goatskin fragments of the Dead Sea Scrolls.
