Ответ:
Option E. "cDNA; DNA"
Explanation:
A DNA microarray is defined as an experiment used to find out the genes which is turned on or turned off in cells or tissues.
The microarray experiment starts with the collection of cancerous and healthy tissue samples from the patient.
The messenger RNA (mRNA) is then isolated from collected sample and is then allowed to color code with fluorescent tags.
This color coded fluorescent mRNA is allowed to make copies of DNA called complementary DNA.
This cDNA then binds to the complementary base pair present in each DNA, process known as hybridization. Based on the complementarity the spot color visible is of green, red yellow et cetera.
Hence the correct answer is option E
