A wide variety of deoxyribonucleases are known and fall into one of two families (DNase I or DNase II), which differ in their substrate specificities, chemical mechanisms, and biological functions. Laboratory applications of DNase include purifying proteins when extracted from prokaryotic organisms.
Deoxyribonuclease I (usually called DNase I), is an endonuclease of the DNase family coded by the human gene DNASE1. [5] DNase I is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average producing tetranucleotides.
The fluids associated with the human body include air, oxygen, carbon dioxide, water, solvents, solutions, suspensions, serum, lymph, and blood. The major body fluid which acts as the lifeline of the living organisms is "Blood". Blood is an extremely complex biological fluid.

Molecular medicine is a broad field, where physical, chemical, biological, bioinformatics and medical techniques are used to describe molecular structures and mechanisms, identify fundamental molecular and genetic errors of disease, and to develop molecular interventions to correct them. [1]
Exodeoxyribonucleases are both exonucleases and deoxyribonucleases. They catalyze digestion of the ends of linear DNA. They are a type of esterase.
The Fanzor (Fz) protein is an eukaryotic, RNA-guided DNA endonuclease, which means it is a type of DNA cutting enzyme that uses RNA to target genes of interest.It has been recently discovered and explored in a number of studies.
In one application an artificial DNA catalyst was prepared by attaching a copper ion to it through a spacer. [46] The copper - DNA complex catalysed a Diels-Alder reaction in water between cyclopentadiene and an aza chalcone. The reaction products (endo and exo) were found to be present in an enantiomeric excess of 50%. Later it was found that ...
