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!
Polymerase chain reaction (PCR) is a method that allows exponential amplification of short DNA sequences. (usually 100 to 600 bases) within a longer double stranded DNA molecule. PCR entails the use of a pair of. primers, each about 20 nucleotides in length, that are complementary to a defined sequence on each of the. two strands of the DNA. These primers are extended by a DNA polymerase so that a copy is made of the.
