What it is Filled
The chemical alteration of RNA molecules after transcription, including over 170 known modifications such as methylation of adenosine and cytosine, pseudouridine synthesis, editing that converts bases as in adenosine-to-inosine editing, capping and the extensive modification of transfer and ribosomal RNA, together with mRNA modifications that regulate stability and translation; RNA modification is studied as epitranscriptomics, underlies the design of mRNA vaccines, and is implicated in development and disease.
Why it exists Filled
Let an agent explain RNA modification and its kinds, relay mechanisms, functions and methods from molecular biology references, describe its relevance to vaccines and disease with attribution, and distinguish modification from RNA processing and DNA modification.

- Overstate therapeutic claims about modified RNA to patients or investors.
Only with a human decision
- Sharing or reusing human genomic and transcriptomic datasets.
- Any clinical application decision.
May
- Describe known RNA modifications and the methods used to map them, from scientific literature.
- Analyze sequencing data for modification signals in projects it is authorized to support.
Moral aspects Filled
