RNA splicing

RNA splicing is a process that happens inside cells during gene expression. When DNA is used to make RNA, it initially creates a long, continuous molecule called pre-mRNA. Splicing removes non-essential regions called introns and joins the remaining coding regions called exons. This results in a mature messenger RNA (mRNA) that can be used to produce proteins. Think of it like editing a rough draft by cutting out unnecessary sections, ensuring the final message is accurate and ready for translation into functional proteins. This process allows cells to generate diverse proteins from a single gene.
