DNA Microarrays Use Enzymes to Convert MRNA Obtained from the Cell

DNA microarrays use enzymes to convert mRNA obtained from the cell into cDNA. This cDNA is hybridized with known DNA from specific genes isolated from the organism. If hybridization occurs, this indicates the cDNA has

A) bound to the corresponding gene and it is being expressed in the cell.
B) transformed into another type of DNA and the corresponding genes are present in the cell.
C) bound to the complementary DNA on the microarray, indicating that the corresponding gene is not being expressed in the cell.
D) not transformed into another type of DNA and the corresponding genes are not present in the cell.
