How do gene chips work
WebFirst, researchers obtain a DNA sample from the patient’s blood as well as a control sample without a mutation in the genes of interest. Researchers then denature the DNA in the samples, cut the DNA into small fragments, and label each fragment with a fluorescent dye. WebDNA chips are miniaturized microsystems based on the ability of DNA to spontaneously find and bind its complementary sequence in a highly specific and reversible manner, known as hybridization. Labeled DNA molecules in a sample are analyzed by DNA probes tethered at distinct sites on a solid support.

WebDNA sequencing is the process of determining the sequence of nucleotide bases (As, Ts, Cs, and Gs) in a piece of DNA. Today, with the right equipment and materials, sequencing a short piece of DNA is relatively straightforward. Sequencing an entire genome (all of an organism’s DNA) remains a complex task. It requires breaking the DNA of the ...
