Question

what is DNA fingerprinting? Where is this technique used? Give any two examples​

Answer 1

hyy mate ✌️

DNA fingerprinting—also known as genetic fingerprinting, DNA typing, and DNA profiling—is a molecular genetic method that enables identification of individuals using hair, blood, semen, or other biological samples, based on unique patterns (polymorphisms) in their DNA.

hope it will help you ❣️

hi mate,

The technique of DNA fingerprinting, which involves comparing samples of human DNA left… The procedure for creating a DNA fingerprint consists of first obtaining a sample of cells, such as skin, hair, or blood cells, which contain DNA. It is also known as genetic fingerprinting, DNA typing, and DNA profiling—is a molecular genetic method that enables identification of individuals using hair, blood, semen, or other biological samples, based on unique patterns (polymorphisms) in their DNA.

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. The profile of repetitive regions in a particular sample represents its DNA fingerprint, which ends up looking a bit like a barcode. Each bar in the barcode represents one particular stretch of repetitive DNA. Since these repetitive regions are common in the genome and highly variable from individual to individual, no two people (except identical twins) will have exactly the same set of repetitive regions and, hence, the same DNA fingerprint.

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.
