Deoxyribonucleic acid (DNA) is a long molecule that contains an animal’s entire genetic code. DNA is primarily located within the nucleus of each cell. In the nucleus, enzymes transcribe the DNA bases into a substance called RNA (ribonucleic acid), which serves as a messenger, taking the DNA message out into the cytoplasm of the cell where the RNA is translated into proteins. These proteins are responsible for a number of functions in the cell and throughout the body, primarily by acting as enzymes that regulate various cell reactions. DNA tests allow us to examine an animal’s DNA in order to see whether they carry certain genetic diseases. DNA testing can also be used to determine the ancestry of an animal.
