Overall, the dna fingerprint does not give any direct information as to the nature of the genes coded for by the dna, and it gives no information about the chemical sequence of the dna it does, however, give direct information about the identity of individual, including their relatedness.
Dna fingerprinting is widely used today for criminal investigation, establishing paternity, in palaeontology, and even in archaeology (dna fingerprinting applications, nd) dna fingerprinting is widely known due to the use of it in criminal investigations and how it’s portrayed on television.

Although dna analysis is sometimes called dna fingerprinting, this term is a misnomer scientific dispute about the validity of the general principles underlying dna evidence, he nevertheless argued that serious problems with dna evidence remained he found particular fault in the work of forensic laboratories and pointed to research that.
Problems with dna fingerprinting like nearly everything else in the scientific world, nothing about dna fingerprinting is 100% assured the term dna fingerprint is, in one sense, a misnomer: it implies that, like a fingerprint, the vntr pattern for a given person is utterly and completely unique to that person.
