Question 1

Degradation of bacterial mRNAs is initiated by:


◦ removal of a pyrophosphate from the 5' terminus.
◦ removal of a diphosphate from the 5' terminus.
◦ removal of a triphosphate from the 5' terminus.
◦ removal of the 3' poly (A) tail.
◦ endonuclease cleavage.

Question 2

In eukaryotes, removal of the 3' poly(A) tail triggers degradation of the mRNA by:


◦ 5'-3' exonucleases only.
◦ 3'-5' exonucleases only.
◦ either 5'-3' or 3'-5' exonucleases.
◦ endonucleases.
◦ random degradation from multiple sites in the transcript.
