Answer 2

"DNA fingerprinting." is the expression known to mean: noun: A method used to identify multilocus DNA banding patterns that are specific to an individual, by exposing a sample of the person's DNA to molecular probes and various analytical techniques. DNA fingerprinting is often used to provide evidence in criminal law cases. Also called genetic fingerprinting. Sources: The American Heritage Medical Dictionary & Mosby's Medical and Dental dictionaries. DNA can be collected from almost all bodily fluids and certain cells. Rather than map the whole 3 billion letters, the process cuts out, by enzyme action, specific sequences of DNA; Arranged by length, the strands are 'tagged' radioactively to emit x-rays. During Photography the emitted x-rays produce the unique 'bar code' of DNA sequences. A genetic 'fingerprint'. The collection, preservation, and processing of DNA evidence is a separate and distinct procedure and discipline than that from collecting, preserving, and identifying latent fingerprints. The two are not compatible, or comparable in any way.

Answer 3

Lifting the prints off of something, the next thing would be placing the 'cloth or item with the lifted fingerprint' under a scanner of some form, which then scans the print into a computer database where it is checked for a match.

Answer 4

There are a great many steps that take place in DNA fingerprinting. The first step is collecting the DNA sample.

Answer 5

The third step in making DNA fingerprints is to scan the fingerprint that you took in step two.
