RNA Processing is a crucial step in the journey from DNA to protein. After transcription, where RNA is synthesized from DNA, the initial RNA molecule, known as pre-mRNA, undergoes several modifications. These include the addition of a 5' cap, which protects the RNA and helps it bind to ribosomes, and a poly-A tail at the 3' end, which aids in stability and export from the nucleus. Additionally, RNA splicing occurs during processing, where non-coding regions called introns are removed, and coding regions known as exons are joined together. This results in a mature mRNA molecule that can be translated into a protein. Proper RNA processing is essential for gene expression and cellular function.
