Deoxyribonuclease II (EC 3.1.22.1, DNase II, pancreatic DNase II, deoxyribonucleate 3'-nucleotidohydrolase, pancreatic DNase II, acid deoxyribonuclease, acid DNase) is an endonuclease that hydrolyzes phosphodiester linkages of deoxyribonucleotide in native and denatured DNA, yielding products with 3'-phosphates and 5'-hydroxyl ends, which occurs as a result of single-strand cleaving mechanism. [1]
DNase I contains four ion-binding pockets, and requires Ca 2+ and Mg 2+ for hydrolyzing double-stranded DNA. [5] Two of the sites strongly bind Ca 2+ while the other two coordinate Mg 2+ . Little has been published on the number and location of the Mg 2+ binding sites, although it has been proposed that Mg 2+ is located near the catalytic ...
Overview of chromatides' and chromosomes' distribution within the mitotic and meiotic cycle of a male human cell. Meiosis occurs in all animals and plants. The result, the production of gametes with half the number of chromosomes as the parent cell, is the same, but the detailed process is different. In animals, meiosis produces gametes directly.

Ribonuclease (commonly abbreviated RNase) is a type of nuclease that catalyzes the degradation of RNA into smaller components. Ribonucleases can be divided into endoribonucleases and exoribonucleases, and comprise several sub-classes within the EC 2.7 (for the phosphorolytic enzymes) and 3.1 (for the hydrolytic enzymes) classes of enzymes.
Bovine pancreatic ribonuclease is the best-studied member of the family and has served as a model system in work related to protein folding, disulfide bond formation, protein crystallography and spectroscopy, and protein dynamics. [2] The human genome contains 8 genes that share the structure and function with bovine pancreatic ribonuclease ...
