MONGOLISM is usually the result of trisomy of a small acrocentric chromosome in Group 21–22 in the Denver Classification. This is generally referred to as 21-trisomy. These patients have a somatic ...

The complete repeating unit of the human ribosomal RNA gene has been reconstructed by the cloning of approximately 27 kilobases (kb) of non-transcribed spacer. The structure of this tandemly repeated gene can now be studied in its entirety. We report

A rapid and sensitive papper electrophoretic assay for 35SO4-containing compounds was developed which allowed measurement of 35S-acid mucopolysaccharides synthesized by skin fibroblasts grown in the presence of inorganic 35S-sulfate. Fibroblasts from

A 16-kilobase region surrounding the transcription initiation site for ribosomal DNA and including the entire ribosomal DNA transcription unit has been characterized in man and compared in higher primates. Restriction analysis of ribosomal DNA from t

Silver-stained chromosomes from 29 couples with a trisomy 21 offspring and from 25 control couples were studied to determine whether there was an association of nucleolar-organizing-region variants in parents of children with trisomy 21. A reproducib

We report the 1,870-base-pair primary sequence of a human 18S rRNA gene and propose a secondary structure based on this sequence and the general mammalian structure. A basic secondary structure for the small subunit rRNA has been preserved throughout

Restriction endonuclease analysis of HeLa cells and cells in which origins have been questioned provides evidence in favor of a HeLa cell origin for the questioned cells. Digestion of cellular human DNA reveals a variable ribosomal DNA (rDNA) fragmen

Two unrelated children, a boy 2 1/2 years old and a girl 4 years old, were affected with the cachectic dwarfism of Cockayne syndrome. Fibroblast cultures derived from these patients exhibited increased sensitivity to ultraviolet (UV) light, but not t

Although the human rDNA gene family is organized in clusters of tandem repeats on five pairs of acrocentric chromosomes, all rDNA genes have undergone a "concerted" evolution resulting in a homogeneous population of genes. Two steps are necessary for
