Why can somebody just replicate the DNA used by PSA/DNA?
It is next to impossible to replicate the DNA that is used to tag each item. PSA/DNA has contracted DNA Technologies, Inc. to create a DNA trace liquid with a code that is known only to PSA and DNA Technologies. The chances are 1 in 33 trillion that someone would be able to randomly recreate the exact sequence of the DNA strand that is used for the PSA/DNA tag.
