【Abstract】 The DNA molecules which could cleave RNA are called DNAzymes or deoxyribozymes.Although they have not been found in nature,some are now in existence thanks to the in vitro selection which designed specifically to derive DNA sequences with RNA cleavage activity.The deoxyribozymes display a high level of substrate specificity and exhibit high catalytic efficiency.With these properties,deoxyribozymes distinguish themselves as potentially useful regent for RNA inactivating.\;更多还原
