deoxyribonuclease (medicine) and era (sh)


deoxyribonuclease (medicine)


deoxyribonuclease
<enzyme> 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.

Acronym: DNAase


era (sh)




Very long span of geologic time; in formal usage, a portion of geologic time of the second-greatest magnitude (eons are longer).

Three eras are recognized: Paleozoic, Mesozoic, and Cenozoic. Because of the difficulties involved in establishing accurate chronologies, the Precambrian, or earliest, eras are classified independently. An era is composed of one or more geologic periods.
