RNA-based programmable DNA cleavage

Natural ribozymes can cleave RNA and single-stranded DNA (ssDNA) by transesterification or a blend of hydrolytic and transesterification reactions. Now, ribozymes have been discovered that catalyze the hydrolytic cleavage of ssDNA. Similar ribozymes could potentially replace large, immunogenic, protein-based nucleases in gene therapies.
