Answer:
Fluorescence in situ hybridization (FISH)
Explanation:
Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to unknown parts of a nucleic acid sequence with a high degree of sequence complementarity. FISH can be used to detect and localize the presence or absence of specific DNA sequences on chromosomes. Â Can also be used to detect and localize specific RNA targets in cells.
