Chromosomal rearrangements in cattle and pigs revealed by chromosome microdissection and chromosome painting [PDF]

open access: yesGenetics Selection Evolution, 2003
A pericentric inversion of chromosome 4 in a boar, as well as a case of (2q-;5p+) translocation mosaicism in a bull were analysed by chromosome painting using probes generated by conventional microdissection. For the porcine inversion, probes specific for p arms and q arms were produced and hybridised simultaneously on metaphases of a heterozygote ...

Contractile acto-myosin network on nuclear envelope remnants positions human chromosomes for mitosis

open access: yeseLife, 2019
To ensure proper segregation during mitosis, chromosomes must be efficiently captured by spindle microtubules and subsequently aligned on the mitotic spindle.

DNA sequence of both chromosomes of the cholera pathogen Vibrio cholerae

open access: yesNature, 2000
Here we determine the complete genomic sequence of the Gram negative, γ-Proteobacterium Vibrio cholerae El Tor N16961 to be 4,033,460 base pairs (bp). The genome consists of two circular chromosomes of 2,961,146 bp and 1,072,314 bp that together encode 3,

Rapid metaphase and interphase detection of radiation-induced chromosome aberrations in human lymphocytes by chromosomal suppression in situ hybridization [PDF]

open access: yes, 1990
Chromosomal in situ suppression (CISS)-hybridization of biotinylated phage DNA-library inserts from sorted human chromosomes was used to decorate chromosomes 1 and 7 specifically from pter to qter and to detect structural aberrations of these chromosomes

Chromosome Centromeres: Structural and Analytical Investigations with High Resolution Scanning Electron Microscopy in Combination with Focused Ion Beam Milling [PDF]

open access: yes, 2009
Whole mount mitotic metaphase chromosomes of different plants and animals were investigated with high resolution field emission scanning electron microscopy (FESEM) to study the ultrastructural organization of centromeres, including metacentric ...

How to identify sex chromosomes and their turnover

open access: yesMolecular Ecology, 2019
Although sex is a fundamental component of eukaryotic reproduction, the genetic systems that control sex determination are highly variable. In many organisms the presence of sex chromosomes is associated with female or male development.

Karyotyping and single-gene detection using fluorescence in situ hybridization on chromosomes of Hydra magnipapillata (Cnidaria: Hydrozoa)

open access: yesComparative Cytogenetics, 2010
The fresh water polyp Hydra L., 1758 (Cnidaria, Hydrozoa) plays a key role as a model organism in modern evolutionary and developmental biology. A complete genome sequence has been published recently for Hydra magnipapillata Ito, 1947 and molecular ...

Factors Impacting Invader-Mediated Recognition of Double-Stranded DNA

open access: yesMolecules, 2022
The development of chemically modified oligonucleotides enabling robust, sequence-unrestricted recognition of complementary chromosomal DNA regions has been an aspirational goal for scientists for many decades.

Detection of chromosome aberrations in metaphase and interphase tumor cells by in situ hybridization using chromosome-specific library probes [PDF]

open access: yes, 1988
Chromosome aberrations in two glioma cell lines were analyzed using biotinylated DNA library probes that specifically decorate chromosomes 1, 4, 7, 18 and 22 from pter to qter.

Cytogenetic studies in the genus Pentaschistis (Poaceae: Arundinoideae)

open access: yesBothalia: African Biodiversity & Conservation, 1998
Cytogenetic studies of 45 specimens, representing 16 taxa of the genus Pentaschistis (Nees) Spach confirmed two basic chromosome numbers (x = 7, 13) for the genus. Chromosome numbers for five species and one subspecies are described for the first time, i.
