RESUMO
We have cloned and characterized Neurospora crassa ribosomal deoxyribonucleic acid (rDNA). The rDNA is found as a tandemly repeated 6.0-megadalton sequence. We have mapped a portion of the rDNA repeat unit with respect to its sites for 13 restriction endonucleases and defined those regions coding for the 5. 8S, 17S, and 26S ribosomal ribonucleic acids (rRNA's). We have also isolated several clones containing 5S rRNA sequences. The 5S rRNA coding sequences are not found within the rDNA repeat unit. We found that the sequences surrounding the 5S rRNA coding regions are highly heterogeneous.
