How is rna is edited prior to leaving the nucleus?

Before RNA leaves the nucleus, it undergoes several editing processes known as RNA processing. This includes the addition of a 5' cap, which protects the RNA and assists in ribosome binding, and a poly-A tail at the 3' end, which aids in stability and export from the nucleus. Additionally, introns, or non-coding sequences, are removed through splicing, while exons, the coding sequences, are joined together to form the mature mRNA. This processed mRNA is then ready to be transported to the cytoplasm for translation.
