Fish staining chromosomes
WebTraditional methods for identifying chromosomes based on large scale (> 100 nm) structure include Giemsa banding (G-banding) method that displays chromosomes having dark (AT rich regions) and light (GC rich … FISH can be used to study the evolution of chromosomes. Species that are related have similar chromosomes. This homology can be detected by gene or genome sequencing but also by FISH. For instance, human and chimpanzee chromosomes are very similar and FISH can demonstrate that two chimpanzee chromosomes fused to result in one human chromosome. Similarly, species t…
