On the number of ribosomal RNA Genes in man

Humangenetik, 1972
The saturation plateau of the high molecular weight species of ribosomal RNA was determined for DNA of human liver from a female and a male person with normal karyotypes. The amount of DNA annealing with (18s+28s) RNA of HeLa cells is equivalent to 443±21 or 416±19 copies of the corresponding gene loci, depending on the set of molecular weights of 18s ...

Regulation of Ribosomal Gene Expression in Cancer

Journal of Cellular Physiology, 2015
The ability of a cell to undergo malignant transformation is both associated with and dependent on a concomitant increase in protein synthesis due to increased cell division rates and biosynthetic activities. Protein synthesis, in turn, depends upon the synthesis of ribosomes and thus ultimately on the transcription of ribosomal RNA by RNA polymerase I

Heterogeneity of the ribosomal genes in mice and men

Cell, 1977
The structures of mouse and human ribosomal DNA were studied using the restriction enzymes Eco R1 and Hind III. Individual mice or humans showed a heterogeneous pattern of restriction fragments resulting from differences in the non-transcribed spacer DNA. Six individual mice from the inbred strain CBA/H-T6 had identical patterns.

Ribosomal RNA Genes and Plant Development

Nature, 1972
The number of copies of the ribosomal RNA genes varies considerably between the different plant species studied. It does seem, however, that there is no gross amplification or deletion of these genes during the development of a particular plant.

Transcription of Ribosomal Genes

1985
Transcription of rRNA genes is the first step in ribosome biogenesis and therefore is crucial in the understanding of the molecular and cellular aspects of ribosome production. Moreover, a specialized cell structure—the nucleolus—is built at the site of the active rRNA genes.

Fine structure of active ribosomal genes

Chromosoma, 1976
The structure of active ribosomal genes in the newt Notophthalmus viridescens has been studied at the higher resolution permitted by negative staining. Spherical particles, 70 A to 100 A in diameter are seen on the non-transcribing "spacer" regions, but were absent from certain regions of the transcribing "matrix". The matrix core often appears thicker
