FAQs
1. What is a DNA microarray?
A DNA microarray is a powerful laboratory tool used to measure gene expression levels on a large scale. It consists of a solid support (usually glass or silicon) with thousands of tiny spots, each containing a unique DNA sequence representing a gene of interest.
2. How does a DNA microarray work?
DNA microarrays work by allowing complementary DNA (cDNA) molecules in a sample to bind to their corresponding DNA sequences on the array. The binding is detected using fluorescent probes, which help identify which genes are being expressed and at what levels in the sample.
3. What can DNA microarrays be used for?
DNA microarrays can be used for a wide range of applications, including gene expression profiling, identifying genetic variations, studying disease mechanisms, predicting drug responses, and personalized medicine.
4. What are the advantages of using DNA microarrays?
DNA microarrays allow for high-throughput analysis, enabling the simultaneous measurement of thousands of genes. They provide valuable insights into gene function, help identify biomarkers, and accelerate the discovery of new therapeutic targets.
5. Are there any limitations to using DNA microarrays?
While DNA microarrays are a powerful tool, they do have limitations. They require prior knowledge of the genes being analyzed, are subject to background noise and potential cross-hybridization, and may not accurately represent the entire transcriptome of an organism.
