RESUMO
The rDNA of Mucor racemosus is contained on a 6.4 megadalton repeat unit. Two Bam H-1 restriction fragments that encompass the entire rDNA repeat, as well as two Hind III restriction fragments that lie within the region, have been cloned and analyzed. The rDNA unit has been defined with respect to eight restriction endonucleases and the position of the sequences encoding the 25S, 18S, and 5.8S rRNA species have been localized. In addition, the 55 RNA encoding sequence was found to reside within the basic repeat unit. The results indicate the organization of the rDNA of Mucor more closely resembles the arrangement observed in yeast than that observed in other eukaryotic organisms.
