Nonfunctional DNA is actually not a very accurate term to call it. What you are referring to is the space of DNA that until recently, scientists believed did nothing for the cell or body. Recently however, it has been found that there are "Switches" that turn on and off the coding for certain characteristics that are read during protein synthesis.
i have no idea so don't ask me, OK
You may be asking about 'Vestigial' organs.
DNA fingerprinting
DNA Polymerase.
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
Nothing gets added on to the DNA. Pol I is suppose to repair damaged sequences , so if it is nonfunctional, the damage sequences remain causing a mutated gene sequence.
mutation
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
Leave out "nonfunctional" and you've got a more or less true statement.

Direct DNA sequencing examines the direct base pair sequence of a gene for specific gene mutations. Some genes contain more than 100,000 bases and a mutation of any one base can make the gene nonfunctional.
