DNA-DNA reassociation experiments show that the genome of Aspergillus nidulans consists of approximately 97 to 98 percent unique and 2 to 3 percent reiterated sequences. The reiterated DNA sequences have a complexity of about 11,000 base pairs and are repeated approximately 60 times per haploid genome. Ribosomal RNA-DNA hybridization experiments indicate that most of the repetitive DNA codes for ribosomal RNA.
