Answer:
Fluorescence in situ hybridization (FISH)
Step-by-step 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. Can also be used to detect and localize specific RNA targets in cells.
