Endonuclease is a nuclease that cleaves polynucleotides into poly - or oligonucleotide fragments of varying size.
restrictive e. One of many endonucleases isolated from bacteria that act as molecular scissors to cut DNA molecules at specific locations; used extensively as a laboratory tool.
Endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain. Some, such as deoxyribonuclease I, cut DNA relatively nonspecifically, while many, typically called restriction endonucleases or restriction enzymes,…
