RNA editing

RNA editing is a biological process where cells modify RNA molecules after they are created from DNA. This editing changes the nucleotide sequences within the RNA, which can alter the proteins that are produced. Think of it as a biological “word edit,” allowing cells to tune proteins for specific needs or adapt to changes. This process helps increase the diversity of proteins without changing the underlying DNA, playing a crucial role in normal development, brain function, and immune responses. RNA editing is a natural way for organisms to add flexibility and regulation to their genetic instructions.
