Fluorescent in situ hybridization (Fish) is a method employing a fluorescent dye covalently bonded to a specific nucleic acid probe identifying or tracking organisms in the environment. Fluorescent in situ hybridization (fish) can be used to determine; how many salmonella typhimurium cells are present in a sample of unpasteurized apple juice, the phylogenetic diversity of an environmental sample and also whether a specific piece of mRNA is being produced.
<span>Remember that of the three Domains, only Eukaryota have multicellular organisms. AllEukaryotes have (or are) complex cells. Plantae, Animalia and Fungi are truemulticellular kingdoms. The various other Eukaryotic kingdoms are lumped under Protists. Hope this helps</span>
