I would need to see a molecular model, or at least a formula, in order to determine hybridization. If you're in the middle of a test right now, you're cheating!
Fluorescent in situ hybridization. Highlights areas of chomosomes. Useful when trying to detemine chromosomal anomalies
It is true that the first activity in test preparation is to determine what the test will be all about.
Diagnosis requires the use of a special test called fluorescence in situ hybridization (FISH) in which a DNA probe for the elastin gene is labeled with a brightly colored fluorescent dye.
