medical dictionary


<cell biology> An endonuclease with preference for DNA. Pancreatic DNAse I yields di and oligo nucleotide 5_ phosphates, pancreatic DNAse II yields 3_ phosphates. In chromatin, the sensitivity of DNA to digestion by DNAse I depends on its state of organisation, transcriptionally active genes being much more sensitive than inactive genes.
