Endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain. Some, such as Deoxyribonuclease I, cut DNA relatively nonspecifically (without regard to sequence), while many, typically called restriction endonucleases or restriction enzymes, cleave only at very specific nucleotide sequences. Restriction enzymes are en...

Nucleases are enzymes that break down nucleic acids into strands of DNA. 'Endo' or inside nucleases act at points along the strand and thus break DNA into short pieces. Endonucleases recognise a particular base sequence in DNA and cut the DNA. Some endonucleases cut the DNA at a specific point while others randomly split the DNA sequences. Specific endonucleases are used by genetic engineers who excise strands of DNA coded for a desirable genetic character. Endonucleases are classed as 'Restriction enzymes' since they are employed e.g., by bacteria to restrict infection by viruses (bacteriophages). The bacterial restriction enzyme attacks the DNA of the infecting organisms....

Ribonucleases such as pancreatic, T1 etc. are specific for RNA, Deoxyribonucleases for DNA. Bacterial restriction endonucleases are crucial in recombinant DNA technology for their ability to cleave double-stranded DNA at highly specific sites.
