Principle of dna fingerprinting
WebA variable number tandem repeat (or VNTR) is a location in a genome where a short nucleotide sequence is organized as a tandem repeat. These can be found on many chromosomes, and often show variations in length (number of repeats) among individuals. Each variant acts as an inherited allele, allowing them to be used for personal or parental ... WebPrinciple of DNA Fingerprinting. DNA is an acronym for deoxyribonucleic acid, a type of nucleic acid found inside every cell in your body. It is a series of chemical molecules that combine to generate irreversible blueprints for life. These are known as bases, and there are four of them. They combine to generate what are known as base pairs.
