title: [Localization of the genes of 28S and 18S RNA in human somatic chromosomes by in situ hybridization].
abstract: In situ hybridization of human somatic cell chromosomes suggests that the genes coding for the 28S and 18S RNA's are located in the satellite of acrocentric chromosomes rather than in the secondary constriction, and that two minor sites exist in the centromeric region of chromosomes 1 and 2.
