The ribosomal genes 18S-25S were then mapped using Fluorescence in situ hybridization (FISH) approach which resulted in the labelling of the Nor genes Nor-B1 and Nor-B 2 as well as the ribosomal genes of lymegrass.
Loks voru 18S-25S ríbósómgen kortlögð með Fluorescence intensity hybridization (FISH) aðferðinni sem sýndi genin Nor-B 1, Nor-B 2 ásamt ríbósómgen melgresis.
