Comments "Some copy number estimates are presented in the table below. The numbers of repeat units in the tandem arrays are variable. In addition, there are numerous orphans and fragments present in the genome. Additional, more distantly related sequences are also likely to be present." ~200 copies of 18S, 5.8S and 28S. There are ~150 copies of 5S. For 150 to 200 copies of rrn genes see PMID 11237011 p.894 right column bottom paragraph
