Question

Quizplus · Accepted Answer

Fluorescent markers commonly used in DNA microarray technology are Cy3 (red) and Cy5 (green) dyes that label DNA fragments. Therefore, the correct options are A (Red) and B (Green). Choice C (Yellow) is incorrect as there is no commonly used yellow dye in DNA microarrays. Choice D (Colorless) and E (None is a correct choice) are also incorrect as fluorescent dyes are required in microarray analysis for visualizing DNA targets on a slide using a fluorescence scanner.
