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!
The Polymerase Chain Reaction (PCR), is the technique used to detect small amounts of DNA and make enough copies of it to be detectable.All cells, bacteria and viruses contain DNA that is unique to them.he prepared sample is then added to a PCR mixture containing small pieces of DNA (primers) which match the DNA we are testing for, building blocks of DNA, and a polymerase enzyme which can join the blocks together to make copies of DNA.
