question 46

Multiple Choice

In an experimental situation, a student researcher inserts an mRNA molecule into a eukaryotic cell after he has removed its 5' cap and poly-A tail. Which of the following would you expect him to find?

• A) The mRNA would not be transported out of the nucleus.
• B) The cell recognizes the absence of the tail and adds a new poly-A tail to the mRNA.
• C) The molecule is digested by restriction enzymes in the nucleus.
