Repeated DNA sequences of Neurospora crassa were isolated and characterized. Approximately 10-12% of N. crassa DNA sequence were repeated, of which 7.3% were found to be transcribed in mid-log phase of mycelial growth as measured by DNA:RNA hybridization. It is suggested that part of repetitive DNA transcripts in N. crassa were mitochondrial and part were nuclear DNA. Most of the nuclear repeated DNAs, however, code for rRNA and tRNA in N. crassa.
粗糙脉孢菌的重复DNA序列被分离并进行了表征。粗糙脉孢菌约10%-12%的DNA序列是重复的，通过DNA:RNA杂交测量发现，其中7.3%在菌丝体生长的对数中期被转录。有人提出，粗糙脉孢菌中部分重复DNA转录本是线粒体的，部分是核DNA的。然而，粗糙脉孢菌中大多数核重复DNA编码rRNA和tRNA。
