The intranuclear organization of normal, hemizygous and excision-deficient rRNA genes during developmental amplification in Tetrahymena thermophila.

Chromosoma - 1 Sept 1997

Ward J G, Blomberg P, Hoffman N, Yao M C

Abstract excerpt

In the ciliated protozoan, Tetrahymena thermophila, the diploid germinal micronucleus contains two allelic copies of the gene for ribosomal RNA (rDNA). During genesis of new somatic macronuclei the germline rDNA gene is excised by developmentally programmed chromosome breakage and preferentially amplified to approximately 9, 000 copies. We have studied this process by fluorescence in situ hybridization. We find...
