Stages of transcription (Initiation (RNA polymerase binds to a sequence of…

- - - - The RNA transcript carries the same information as the non-template strand of DNA
        
        But the complementary base uracil (U) is added instead of thymine (T).
- - - - What is it?
        
        The starting point for capping with 7-methylguanylate is the unaltered 5′ end of an RNA molecule, which terminates at a triphosphate group.
        
        Functions
        
        Protects the mRNA molecule from enzymatic degradation
        
        Aids in transcription termination
        
        Exports of the mRNA from the nucleus
      - Functions
        
        Regulation of nuclear export
        
        Prevention of degradation by exonucleases
        
        Promotion of translation
        
        Promotion of 5′ proximal intron excision
    - - What is it?
        
        The poly(A) tail consists of multiple A bases
    - - In this process, introns (no coding) are chopped out, and exons (coding) are stuck back together.
