Questions

1. What is a DNA microarray?

A protein synthesis instrument
A genetic sequencing device
A DNA amplification tool
A high-throughput method used to measure expression levels of large numbers of genes simultaneously

2. How does the DNA microarray work?

By accelerating DNA particles
By scanning the entire human genome
By detecting the presence of specific proteins
By observing the binding of fluorescently labeled DNA or RNA

3. In the simulation, what does the green color indicate?

The gene is not expressed in either the normal or cancer cells
The gene is mutated in the cancer cells
The gene is underexpressed in the cancer cells
The gene is overexpressed in the cancer cells

4. What does the red color indicate in the simulation?

The gene is not expressed in either the normal or cancer cells
The gene is overexpressed in the cancer cells
The gene is underexpressed in the cancer cells
The gene is mutated in the cancer cells

5. What does the yellow color indicate in the simulation?

The gene is expressed equally in both the normal and cancer cells
The gene is not expressed in either the normal or cancer cells
The gene is mutated in the cancer cells
The gene is overexpressed in the cancer cells

6. What does a black spot on the microarray represent?

The gene is overexpressed in the cancer cells
The gene is mutated
The gene is underexpressed in the cancer cells
The gene is not expressed in either sample

7. What is the primary purpose of a DNA microarray assay?

To compare gene expression between two different samples
To identify the presence of specific proteins
To clone DNA sequences
To sequence the entire genome

8. Why are two different fluorescent dyes used in the simulation?

To distinguish between normal and cancer cells
To mark the beginning and end of the DNA sequence
To indicate the level of gene expression
To identify mutated genes
