Fluorescence in Situ hybridization (FISH):
A process that identifies chromosomal abnormalities, such as deletions (when part of a chromosome is left out), duplications (when genes are duplicated in the same chromosome), and translocations (when part of a chromosome breaks off and is added to another chromosome)
SUBSTANCES INVOLVED IN FISH:
Step Two: The DNA strands from the target sequence and probe are mixed. If hybridization (combination of two complementary single strands) is present, then it will be easily seen under the fluorescence microscope. The result will be analyzed to determine if any diseases are present.
