One method for localizing a piece of DNA within a genome is called fluorescence in situ hybridization, abbreviated FISH.
FISH in thick tissue sections: FISH has the potential to provide genetic information from individual cells.

FISH permits analysis of proliferating (metaphase cells) and non-proliferating (interphase nuclei) cells and is useful in determining the percentage of neoplastic cells before and after therapy (minimal residual disease) (see examples at ...
In this newer technique, several different probes specific of one chromosome pair, carrying different amounts of a set of fluorescent dyes, are hybridized to the chromosomes in a technique known as fluorescent in situ hybridization (FISH).
