You are investigating an abnormal eukaryotic cell line that makes all of its mRNAs much longer than the mRNAs from normal cells (that is, they have more nucleotides than usual). Intrigued, you examine the proteins in these abnormal cells and note that
many of them are either much longer or much shorter than the normal proteins from nonmutant cells. Assuming there is just one mutant defect in these cells, what is that defect? A. A stop codon is mutated. B. RNA polymerase does not recognize the terminator sequence. C. Release factor is defective. D. The spliceosome is nonfunctional. E. The enzyme that adds the poly-A tail is defective.
In Caenorhabditis elegans vulval development, the fate of the progenitor cells is dependent on their proximity to the ____ cell, which secretes epidermal growth factor

Investigators have found a new species bacteria that lives under both aerobic and anaerobic conditions. They hypothesize that different genes are expressed in each condition. What experiment could test this hypothesis and identify important genes?
A. Design primers to a specific region of the genome and sequence this region during both anaerobic and aerobic conditions B. Completely sequence the genome of the bacteria in both aerobic and anaerobic conditions C. Collect mRNA from both anaerobic and aerobic conditions and generate two cDNA libraries D. Measure levels of RNA Polymerase in both conditions
