Where is messenger rna edited in to its final form?

Messenger RNA (mRNA) is edited into its final form in the nucleus of eukaryotic cells. During this process, introns are removed and exons are spliced together, a process known as RNA splicing. Additionally, modifications such as the addition of a 5' cap and a poly-A tail occur, which are crucial for mRNA stability and translation. Once these modifications are complete, the mature mRNA is transported to the cytoplasm for protein synthesis.
