Question #2
An important difference between mRNA and DNA is:
A.   mRNA can move throughout the cell, while DNA stays in the cytosol. 
B.   DNA can move throughout the cell, while mRNA stays in the nucleus.
C.   mRNA can move outside of the cell, while DNA stays inside the cell.
D.   mRNA contains uracil instead of thymine, which is found in DNA.

Question #4
In bacteria, the antibiotic tetracycline blocks the site where tRNA molecules enter the ribosome.  The MOST likely reason the bacteria die from treatment with tetracycline is because the antibiotic:
