Which of the following statements regarding the comparison of DNA microarrays and qPCR is false?

While DNA microarrays can be used to determine whether or not a gene is expressed in a cell, quantitative polymerase chain reaction (qPCR) can be used to measure the extent of gene expression in cells and tissues. To perform qPCR, mRNA is extracted from cells and reverse transcribed to complementary DNA (cDNA). Using fluorescent DNA molecules that recognize specific gene sequences and DNA polymerase, copies of the gene sequence of interest are made. After the copies are made, a fluorescent detector measures the intensity of the fluorescent signal, which is proportional to the number of mRNA transcripts in the cell and corresponds to the level of gene expression in the cell.

A) Both methods use fluorescent DNA molecules and cDNA.
B) Both methods can determine whether a gene has been turned on or not.
C) Both methods use mRNA extracted from cells.
D) Both methods can quantify the levels of gene expression in cells.
