The ratio of different-colored fluorescent dyes in microarray can be used to infer information about:

A) patterns of gene expression only
B) drug activity only
C) the identity of disease-causing genes only
D) patterns of gene expression and also drug activity only
E) patterns of gene expression, drug activity, and the identity of disease-causing genes

Fluorescent Dyes

Chemical compounds that absorb light at one wavelength and emit it at another, used to stain and visualize biological molecules or cells under a microscope.

Microarray

A laboratory tool used to detect the expression of thousands of genes at the same time, allowing researchers to understand complex genetic processes.

Gene Expression

The process by which information from a gene is used to synthesize a functional gene product, often a protein, influencing the cell's structure and function.
