XX/XY Sex Chromosomes in the South American Dwarf Gecko (\u3cem\u3eGonatodes humeralis\u3c/em\u3e) [PDF]
, 2018 Sex-specific genetic markers identified using restriction site-associated DNA sequencing, or RADseq, permits the recognition of a species’ sex chromosome system in cases where standard cytogenetic methods fail.

The Transmembrane Protein Semi1 Positions Gamete Nuclei for Reciprocal Fertilization in Tetrahymena
iScience, 2020 Summary: During sexual reproduction in the ciliate, Tetrahymena thermophila, cells of complementary mating type pair (“conjugate”) undergo simultaneous meiosis and fertilize each other.

Nature Communications, 2018 Chromosome instability is associated with cancer formation. Here the authors identify in cultured human cancer cells a non-canonical DNA bridge breakage pathway leading to chromosome missegregation and rearrangements triggered by sister DNA ...

Pharmacology Research & Perspectives, 2022 UDP‐glucuronosyltransferases (UGTs) catalyze the conjugation of various substrates with sugars. Since the UGT2 family forms a large cluster spanning 1.5 Mb, transgenic mouse lines carrying the entire human UGT2 family have not been constructed because of

Resolving the degree of order in the bacterial chromosome using a statistical physics approach [PDF]
arXiv, 2020 While bacterial chromosomes were long thought to be amorphous, recent experiments reveal pronounced organizational features. However, the extent of bacterial chromosome organization remains unclear. Here, we develop a fully data-driven maximum entropy approach to extract the distribution of single-cell chromosome conformations from experimental ...

Why Y chromosome is shorter and women live longer? [PDF]
Eur. Phys. J. B 65, 149-153 (2008), 2008 We have used the Penna ageing model to analyze how the differences in evolution of sex chromosomes depend on the strategy of reproduction. In panmictic populations, when females (XX) can freely choose the male partner (XY) for reproduction from the whole population, the Y chromosome accumulates defects and eventually the only information it brings is a

Double in situ hybridization in combination with digital image analysis: A new approach to study interphase chromosome topography [PDF]
, 1989 Double in situ hybridization with mercurated and biotinylated chromosome specific DNA probes in combination with digital image analysis provides a new approach to compare the distribution of homologous and nonhomologous chromosome targets within ...

Improving the Search by Encoding Multiple Solutions in a Chromosome [PDF]
Evolutionary Machine Design, Nova Science Publisher, New-York,
edited by Nadia Nedjah (et al.), pp. 81-107, 2004, 2021 We investigate the possibility of encoding multiple solutions of a problem in a single chromosome. The best solution encoded in an individual will represent (will provide the fitness of) that individual. In order to obtain some benefits the chromosome decoding process must have the same complexity as in the case of a single solution in a chromosome ...

Chromosome breakage after G2 checkpoint release [PDF]
, 2006 DNA double-strand break (DSB) repair and checkpoint control represent distinct mechanisms to reduce chromosomal instability. Ataxia telangiectasia (A-T) cells have checkpoint arrest and DSB repair defects. We examine the efficiency and interplay of ATM's

Chromosome Evolution: The Junction of Mammalian Chromosomes in the Formation of Mouse Chromosome 10 [PDF]
Genome Research, 2000 During evolution, chromosomes are rearranged and become fixed into new patterns in new species. The relatively conservative nature of this process supports predictions of the arrangement of ancestral mammalian chromosomes, but the basis for these rearrangements is unknown.
