Secondly, What is the DNA microarray technique?

Microarray technology is a generic laboratory technique that includes attaching an array of hundreds to millions of known nucleic acid fragments to a solid surface called a “chip.” After that, the chip is soaked with DNA or RNA extracted from a research sample (such as cells or tissue).

Also, Which of the following is correct about microarray?

ForumQue is a discussion forum. Which of the following statements regarding a microarray is incorrect? b.CDNAsc cannot be made from an array of immobilized DNA oligomers. Each oligomer is placed on the slide as a probe for binding to a specific complementary cDNAd. It is the most widely used approach for global gene expression profiling1. row

People also ask, What are limitations of DNA microarray technology?

The most notable drawbacks of microarrays are the expensive cost of a single experiment, the enormous number of probe designs based on low-specificity sequences, and the lack of control over the pool of examined transcripts, since most frequently used microarray systems employ just one set of probes.
