DNA contamination is an important issue in a criminal laboratory, because it can impact the outcome of a case in ways which can send innocent people to jail or set free someone who is guilty. A few ways that DNA can be contaminated areÊby transfer of DNA in the lab due to improper handling and by making assumptions about the presence of DNA on an object without verifying how it may have gotten there by examining other evidence to corroborate theories.
When there's a mutation, which can vary from point-mutation where one nucleotide is misplaced, to chromosomal mutations, where a chunk of chromosome is misplaced.
The process is referred to as gel electrophoresis. This is an analytical process where DNA fragments can be separated based on size within a gel under the influence of an electric field
Gel electrophoresis
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.
it is called " electrophoresis"
DNA samples are within the gel matrix during electrophoresis. DNA moves at differtent rates through the pores of the gel depending on how long the fragments are. DNA is held by the gel itself.

Gel electrophoresis
Agarose gel electrophoresis is suitable for ALL DNA.
For larger molecules like proteins we use polyacrylamide gel electrophoresis (PAGE). For smaller pieces like DNA we use agarose gel electrophoresis

Gel electrophoresis is an analytical method used to separate DNA, RNA or proteins based on size
Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.
