You are working in a cancer lab and are interested in identifying some genes that are important in the onset of lung cancer. You have several genes you think may be involved, so you "print" spots of the DNA sequences of interest on a microarray slide. After doing this, you isolate mRNA from both normal lung cells and cancerous lung cells. Before you use these mRNAs to probe the microarray slide, you need to
A. make cDNA and amplify the cDNA using PCR. B. amplify the mRNA using PCR. C. clone each mRNA into a BAC vector. D. add reverse transcriptase and fluorescent nucleotides to the mRNA to make cDNA. E. sequence the mRNA.

A sample of milk is tested for its bacterial content in a plate count assay. A one-milliliter sample of the milk is diluted in a 1:10 dilution series. One milliliter of the third dilution tube is plated in a pour plate. After incubation, the plate has 54 colonies, indicating that the original milk sample contained
A) 54 cells per milliliter. B) 540 cells per milliliter. C) 5,400 cells per milliliter. D) 54,000 cells per milliliter. E) 540,000 cells per milliliter.
