WebJan 5, 2024 · The researchers showed that in zebra fish, loss-of-function mutations in the leucine transporter cause all fins to be short, while the overexpression mutation of the potassium channels causes all fins to be long. Either of those mutations by itself produces a clumsy fish. But when the two mutations are combined, the resulting zebra fish has ... FISH is a technique that uses fluorescent probes to detect specific genes or parts of genes (DNA sequences). Medical center lab personnel and oncologists use FISH to help assess patients who may have cancer, and sometimes to monitor a patient who has already been diagnosed with cancer and treated.2 FISH … See more The “H” in FISH refers to hybridization. In molecular hybridization, a labeled DNA or RNA sequence is used as a probe—visualize a red Lego brick, if you will. The probe is … See more FISH and other in situ hybridization procedures are used to diagnose a variety of chromosomal abnormalities—changes in the genetic material, changes in chromosomes, … See more An advantage of FISH is that it doesn't have to be performed on cells that are actively dividing. Cytogenetic testing usually takes about three weeks, because the cancer cells must grow in lab dishes for about 2 weeks … See more cytoplasmic antibody ana
