Bergmann’s rule: populations in colder climates tend to have greater body mass than those in warmer climates. This pattern is so common that it has a name

nonstop-mediated decay rescues ribosomes that translate mRNAs that lack a stop codon. When an mRNA lacking a stop codon is translated, the ribosome translates through the poly-A tail This results

mRNP export from the nucleus into the cytoplasm is controlled by the phosphorylation and dephosphorylation of mRNP adapter proteins, REF, the NXF1/NXT1 mRNP exporter to mRNPs.

SR Proteins, in its phosphorylated form, the SR protein initially binds to nascent pre-mRNA. When 3′ cleavage and polyadenylation are completed, the adapter protein is dephosphorylated by a specific nuclear protein phosphatase that is essential for mRNP export. Only the dephosphorylated adapter protein can bind the mRNP exporter, thereby coupling mRNP export to correct polyadenylation.
