WebIn this section we discuss the background knowledge you will need when deciding whether to order chromosomal microarray, including how the test works, what it detects, and when it has proven useful. Below are key questions you should understand before deciding to test with chromosomal microarray. Applying Results. CMA Ordering. 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.
