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.

The hypothesis that whether the poly (A) tail degrade after certain limit or not certain limit can be detected  by  critically analyzing the sample containing bulk amount mRNA (messenger ribonucleic acid). If certain parts were found having certain minimum length, then the hypothesis would be correct. This would show that all the mRNAs with short tails have got degraded.
