Endonuclease: An enzyme which digests nucleic acids starting in the middle of the strand (as opposed to an exonuclease, which must start at an end). Examples include the restriction enzymes, DNase I and RNase A.

A restriction enzyme (or restriction endonuclease) is an enzyme that cuts double-stranded DNA. The enzyme makes two incisions, one through each of the phosphate backbones of the double helix without damaging the bases.

Restriction enzyme More correctly called a Type II Restriction Endonuclease. A bacterial enzyme which forms part of a system to protect the cell against infection by bacteriophage, and unregulated influx of foreign DNA.

At the entry site, endonucleases cut the DNA into fragments of 7,000-10,000 nucleotides, and the double-stranded DNA separates into single strands. The single-stranded DNA may recombine with the host's chromosome once inside the cell.

The DNA is then cut into restriction fragments by endonucleases, which only cut where there are specific DNA sequences recognized by the enzymes. The restriction fragments are then separated according to length by agarose gel electrophoresis.
