They cut strands of DNA at specific sites.
restriction enzymes
Restriction enzymes, also known as restriction endonucleases, are used to cut DNA into smaller fragments. Restriction enzymes are found in bacteria, where they act like molecular scissors by cutting up DNA from invading viruses or bacteriophages. Each restriction enzyme recognizes a specific nucleotide sequence and cuts the DNA at that site. This process makes restriction enzymes extremely useful in biotechnology where they are used in procedures such as DNA cloning, DNA fingerprinting, and genetic engineering. There are hundreds of known restriction enzymes, and each one was named for the bacteria from which it was isolated. For example, EcoRI was isolated from Escherichia coli and HaeIII from Haemophilus aegyptius.
Biotechnologists use enzymes called restriction enzymes to cut DNA molecules at specific sequences. These enzymes recognize particular DNA sequences and cut the DNA at those specific locations, allowing for precise manipulation of genetic material.
Bio technologists use restriction enzymes to cut DNA molecules at specific sequences. These enzymes recognize specific sequences of nucleotides and cleave the DNA at those sites, allowing for precise manipulation of the DNA.
restriction endonuclease
restriction enzymes
A restriction enzyme (or restriction endonuclease) is an enzyme that cuts double-stranded or single stranded DNA at specific recognition nucleotide sequences called restriction sites.
Bacterias use restriction enzymes as a form of defense mechanism. We as people use these restriction enzymes in bacterias to aid us in genetic engineering.

The use of RFLPs in generic fingerprinting is based on the ability of restriction enzymes to dissect DNA into small fragments. There are many kinds of restriction enzymes made to cut various DNA sequences.

restriction endonuclease
We believe the function of the restriction enzyme is to protect an organism from foreign DNA as restriction enzymes cleave DNA strands (making them useless). The idea is that bacteria use this to protect against viral infection as viruses attach to the cell and insert their DNA into it in order to "take over" the cell. Restriction enzymes recognize this DNA as foreign and begin to chop it up, saving the cell.
