Restriction enzyme is a type of enzyme that is able to cut double stranded and single strand DNA from
a certain part that composed of specific nucleotide sequences which is literally called as restriction sites. In prokaryotic
organisms this enzyme used as a defense mechanism for the host cells as it can degrade foreign organisms (mainly viruses) DNAs.
However, as foreign DNA is degrading, host cell protects its own DNA by the addition of methyl group
to its DNA with the help of a modification enzyme (methylase).
There are more than 2000 restriction enzymes can be found and over 600 are ready for commercial usages like DNA
modification.
