In eukaryotic cells, mRNA decay is catalyzed by two major pathways, and both can be initiated by deadenylation of the polyadenylated (poly-A) tail. After decapping, 5’ to 3’ RNA degradation is ...
It acts like a skilled architect, carefully laying down the blueprint for the mRNA that mirrors the DNA template. In eukaryotic cells, RNA polymerase II is specifically responsible for synthesizing ...
