Description
DNase I is a deoxyribonuclease that requires a divalent cation and can be used to degrade single stranded or double stranded DNA. The principle is that DNase I hydrolyzes phosphate diester bonds to produce single nucleotides or oligonucleotides with 5 '- phosphate groups and 3' - OH groups. Both Mg2+ and Mn2+ can activate the activity of DNase I, while Ca2+ concentration directly affects enzyme activity. When Mg2+ is present, it can randomly generate incisions on each single strand of double stranded DNA; In the presence of Mn2+, double stranded DNA can be broken and fragmented. Used for the preparation of RNA without DNA contamination, reverse transcription, and in vitro transcription experiments.
