Ribozymes cleave the
Webb23 sep. 2024 · The ribozyme motif mediates both cleavage and end joining processes, resulting in a combination of interconvertible linear and circular satellite RNA molecules. … WebbRNA ends obtained by in vitro transcription using T7 RNA polymerase are often heterogeneous in length and sequence. An efficient strategy to overcome these drawbacks consists of inserting an RNA with known boundaries in between two ribozymes, usually a 5' hammerhead and a 3' hepatitis delta virus ribozymes, that cleave off the desired RNA.
