A nuclear stress test is one of several types of stress tests that may be performed alone or in combination. Compared with an exercise stress test, a nuclear stress test can help better determine your risk of a heart attack or other cardiac event if your doctor knows or suspects that you have coronary artery disease.
DNA microarray analysis is one of the fastest-growing new technologies in the field of genetic research. Scientists are using DNA microarrays to investigate everything from cancer to pest control. Now you can do your own DNA microarray experiment!
Definition: DNA (deoxyribonucleic acid) is a type of macromolecule known as a nucleic acid.It is shaped like a twisted double helix and is composed of long strands of alternating sugars and phosphate groups, along with nitrogenous bases (adenine, thymine, guanine and cytosine).NA contains the genetic information necessary for the production of other cell components, organelles, and for the reproduction of life. Information contained within the genetic code is passed from DNA to RNA to the resulting proteins.
