What are DNA microarrays? How are they used?

Video transcript

Hey, everyone, let's take a look at this question together which of the following statements is true about D N A micro arrays. Well, we know that D N A micro arrays are used to simultaneously measure the expression level of several jeans. And so looking at the following answer choices, which one is a true statement? Well, answer choice A says that it is a method for quantifying the expression of proteins which is incorrect because the expression of proteins is not measured directly. Answer choice B says that it is a technology for identifying single nucleotide polymorphisms or SNPs, which we know is also incorrect because it is not designed to identify SNPs. Answer. Choice C says that it is a tool for studying levels of gene expression which we know those micro rays are used to simultaneously measure expression level of several genes. So answer choice C is a true statement about D N A micro rays. And so it is the correct answer. And lastly answer choice D says that it is a tool for studying interactions between DNA and proteins which we know is also incorrect. Since the interaction between DNA and proteins are also not measured directly. And so answer choice C is the only true statement here about D N A micro arrays because we know that it is a tool for studying levels of gene expression. I hope you found this video to be helpful. Thank you and goodbye.
