In a genome-wide expression study using a DNA microarray assay, each spot is used to detect D) expression of a specific gene by a cell.

A DNA microarray assay can be described as an assay technique in which each of gene of an organism can be studied.

Each gene that is present inside an organism is distributed or captured in a well-known spot using the DNA microarray technique. This is because there is a complementary sequence present in each well for each gene.

We can study the expression of a specific kind of gene as the entire genomic sequence is separated into spots using the DNA microarray assay.

Although a part of your question is missing, you might be referring to this question:

A) fate of proteins produced by a cell.

B) location of a protein produced by a cell.

C) location of a gene within a cell.

D) expression of a specific gene by a cell.

E) type of chemical modification of proteins produced by a cell.
