Dormant ascospores contain the same ribosomal population as growing hyphae and resting conidia. This conclusion is based on analyses of sedimentation coefficients and of nucleotide composition of ribosomes, ribosomal RNA, and soluble RNA. Thus dormancy is not characterized by the absence of the important parts of the protein-synthesizing apparatus.
