The chemical structure of RNA is very similar to that of DNA, but differs in three primary ways: . The dual-tracrRNA:crRNA, when engineered as a single RNA chimera, also directs sequence-specific Cas9 dsDNA cleavage. The chemical structure of RNA is very similar to that of DNA, but differs in three primary ways: . Circular RNAs have recently been shown to have protein-coding potential. Here the authors design a self-splicing RNA that, when circularized, provides for stable high-yield protein production. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA (mRNA). RNA-targeting CRISPRCas13 systems have been harnessed for a variety of applications 1, including programmable RNA editing 2,3. Cas9, the hallmark protein of Type II systems, has been hypothesized to be involved in both crRNA maturation and crRNA-guided DNA interference (4, 25-27).Cas9 is involved in crRNA maturation (), but its direct participation in target DNA destruction has not been investigated.To test whether and how Circular RNA (or circRNA) is a type of single-stranded RNA which, RNAs can undergo base modification by RNA editing after transcription. Current methods for programmed RNA editing using endogenous ADAR enzymes and engineered ADAR-recruiting RNAs (arRNAs) suffer from low efficiency and bystander off-target editing. The ADAR enzyme and its associated gene were discovered accidentally in 1987 as a result of research by Brenda Bass and Harold Weintraub. The native CRISPR array, comprising four repeat and three spacer sequences, encodes mature CRISPR RNAs (crRNAs) that we also refer to as guide RNAs. Unlike double-stranded DNA, RNA is usually a single-stranded molecule (ssRNA) in many of its biological roles and consists of much shorter chains of nucleotides. They occur naturally, serving important functions, but can also be designed to be used for targeted editing, such as with CRISPR-Cas9 and CRISPR-Cas12.

They occur naturally, serving important functions, but can also be designed to be used for targeted editing, such as with CRISPR-Cas9 and CRISPR-Cas12. The major determinant of editing for human APOBECs is the 1 base, thus defining typical dinucleotide targets (the edited base and the 1 base).
