and generally represents a transition from gonochorism to hermaphroditism (as in the androdioeciousCaenorhabditis elegans), likely due to selection for reproductive assurance rather than the reverse direction of change2,9,10,11. In animals, transitions from hermaphroditic ancestors to androdioecy ...

Insight into the Genome of Diverse Penicillium chrysogenum Strains: Specific Genes, Cluster Duplications and DNA Fragment Translocations Four chromosomes were resolved in and by pulse field gel electrophoresis. The genomes of three industrial strains have a similar size but contain gene duplications and ...
Therefore, if recombination has authentically ceased between neo-Y and neo-X, then we would expect a reduced DNA polymorphism caused by reduced N e for the neo-Y regions [6, 27]. Otherwise, the polymorphism level of neo-Y should be similar to that of 'PAR' regions or autosomes. ...
Binding of anti-Z-DNA antibodies in quiescent and activated lymphocytes: relationship to cell cycle progression and chromatin changes Although regions of DNA reacting with anti-Z-DNA antibodies have been identified in the polytene chromosomes of Drosophila spp. and the metaphase chromosom...

complex in the sex chromosomes of three groups of organisms, namely: mammals, orthopterans, and hemipterans, which present different patterns of sex chromosome structure and behavior. Of special interest is the analysis of the organization of the axial/lateral elements of the synaptonemal complex in...

Micronuclei, which are common features of nuclei in cancer cells, can generate heritable sources of transcriptional suppression, a finding that establishes an inherent relationship between chromosomal instability and variation in chromatin state and gene expression. ...
