Colors+of+DNA+Microarrays

A. **__Green__** 1. Represents control DNA 2. Where DNA or cDNA derived from normal tissue hybridized with the target DNA

B. __**Red**__ 1. Represents sample DNA 2. Where DNA or cDNA derived from diseased tissue hybridized with the target DNA

C. **__ Yellow __** 1. Represents a combination of both control and sample DNA 2. Both parts are equally hybridized to the target DNA

D. **__Black__** 1. Represents areas where neither control or sample DNA hybridized to the target DNA.

E. __**Color intensity**__ 1. Will tell whether the gene or mutation is present in either the control or the sample DNA. 2. Provides an estimation of the expression level of the gene or genes in the sample and control DNA.
