Some years ago, it was suggested that the function of the poly(A) tail on a eukaryotic message may be to ′′ticket′′ the message. That is, each time the message is used, one or more residues is removed, and the message is degraded after the tail is shortened below a critical length. Suggest an experiment to test this hypothesis. Match the words in the left column to the appropriate blanks in the sentences on the right.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
