fluorescent in situ hybridization

initialism: FISH
mentioned: long non-coding ribonucleic acid (lncRNA), messenger ribonucleic acid (mRNA), mitochondrial ribonucleic acid (miRNA))

Cytogenetic technique used to detect and localise the presence or absence of specific deoxyribonucleic acid (DNA) sequences on chromosomes. It uses fluorescent probes that only bind to those parts of the chromosome with which they show a high degree of sequence complementarity.
Note: FISH is often used for finding specific features in DNA for use in genetic counselling, medicine, and species identification. FISH can also be used to detect and localise specific ribonucleic acid (RNA) targets (messenger ribonucleic acid (mRNA), long non-coding ribonucleic acid (lncRNA) and mitochondrial ribonucleic acid (miRNA)) in cells, circulating tumour cells, and tissue samples. In this context, it can help define the spatial-temporal patterns of gene expression within cells and tissues.
