Mixing device for generating simple chromatographic gradients (1965)
Hegenauer, John C., Tartof, Kenneth D., Nace, George W.
A linear gradient device consisting of two concentric reservoirs of equal cross-sectional area, in which the initial and limiting eluent solutions are maintained in hydrostatic equilibrium, may be...
Evolution of the Transcription Unit of Ribosomal RNA*
Perry, Robert P., Cheng, Tsai-Ying, Freed, Jerome J., Greenberg, Jay R., Kelley, Dawn E., Tartof, Kenneth D.
In eukaryotes the two principal RNA components of the ribosomes are initially synthesized as a large complex precursor molecule, which may be thought of as a transcription unit. The precursor is...
Unequal Mitotic Sister Chromatid Exchange as the Mechanism of Ribosomal RNA Gene Magnification
It is hypothesized that magnification of the gene coding for ribosomal RNA occurs by unequal mitotic sister chromatid exchange on the basis of five different lines of evidence. These are: (1) rDNA...
The Effect of mei-41 on Rdna Redundancy in DROSOPHILA MELANOGASTER
Hawley, R. Scott, Tartof, Kenneth D.
The recombination and repair defective mutant, mei-41, exhibits three rather striking effects on the genetic properties and chromosomal stability of rDNA in Drosophila. First, mei-41 inhibits rDNA...
A Two-Stage Model for the Control of rDNA Magnification
Hawley, R. Scott, Tartof, Kenneth D.
Males of the genotype bb/Ybb- have been shown to produce both magnified (bbm+) and, less frequently, reduced (bbrl) X chromosomes. An analysis of the progeny of single magnifying bb/Ybb- males...
Regulation of Ribosomal RNA Gene Multiplicity in DROSOPHILA MELANOGASTER
The ribosomal RNA (rRNA) genes of Drosophila melanogaster can undergo a disproportionate replication of their number. This occurs when the cluster of rRNA genes (rDNA) of one chromosome is maintained...
Genetic Analysis of the 5s RNA Genes in DROSOPHILA MELANOGASTER
Procunier, James D., Tartof, Kenneth D.
The 5S RNA genes of Drosophila melanogaster in either an isogenic wild-type or a multiply inverted (SM1) chromosome 2 increase their multiplicity when opposite a deficiency for the 5S gene site. This...
Procunier, James D., Tartof, Kenneth D.
The results of deficiency mapping experiments reveal the presence of a compensatory response (cr+) locus that is located distal to the cluster of ribosomal RNA (rRNA) genes and is responsible for...
