| Description: The torpedo model of eukaryotic transcription termination. Eukaryotic transcription leads to torpedo RNase association with mRNA , Enzymatic cleavage near the poly-A-signal sequence releases the mature mRNA. The torpedo RNase attacks the uncapped 5ˊ end of the residual mRNA and digests it , leading RNA polymerase II to dissociate from the DNA and the torpedo RNase The torpedo model of eukaryotic transcription termination.
