Question

Quizplus · Accepted Answer

FISH (Fluorescence In Situ Hybridization) is a molecular cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity. It is primarily used for identifying the chromosomal location or position of a gene or DNA sequence on the chromosomes. This technique does not determine the order of DNA fragments in a BAC, the pattern of expression of a cloned gene, or the map order of two closely linked genes.
