Introns are added to the rna

WebPre-mRNAs are first coated in RNA-stabilizing proteins; these protect the pre-mRNA from degradation while it is processed and exported out of the nucleus. The three most important steps of pre-mRNA processing are the addition of stabilizing and signaling factors at the 5′ and 3′ ends of the molecule, and the removal of the introns ( (Figure) ). WebIntrons can significantly affect gene expression in plants and many other eukaryotes in a variety of ways. Several types of gene regulation, both positive and negative, that involve plant introns are reviewed in this chapter. Some introns contain enhancer elements or alternative promoters, while many others elevate mRNA accumulation by a ...

The final … WebThe process of removing introns and reconnecting exons is called splicing (Figure 9.18). Introns are removed and degraded while the pre-mRNA is still in the nucleus.
