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

Mitotic chromosomes

open access: yesSeminars in Cell & Developmental Biology, 2021
Our understanding of the structure and function of mitotic chromosomes has come a long way since these iconic objects were first recognized more than 140 years ago, though many details remain to be elucidated. In this chapter, we start with the early history of chromosome studies and then describe the path that led to our current understanding of the ...

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.

Ki-67 acts as a biological surfactant to disperse mitotic chromosomes

open access: yesNature, 2016
Eukaryotic genomes are partitioned into chromosomes that form compact and spatially well-separated mechanical bodies during mitosis. This enables chromosomes to move independently of each other for segregation of precisely one copy of the genome to each ...

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.

A fragmented metazoan organellar genome [PDF]

open access: yes, 2008
Background: Animal mitochondrial (mt) genomes are characteristically circular molecules of ~16–20 kb. Medusozoa (Cnidaria excluding Anthozoa) are exceptional in that their mt genomes are linear and sometimes subdivided into two to presumably four ...

DNA methylation profiling of human chromosomes 6, 20 and 22

open access: yesNature Genetics, 2006
DNA methylation is the most stable type of epigenetic modification modulating the transcriptional plasticity of mammalian genomes. Using bisulfite DNA sequencing, we report high-resolution methylation profiles of human chromosomes 6, 20 and 22, providing

Rapid generation of chromosome-specific alphoid DNA probes using the polymerase chain reaction [PDF]

open access: yes, 1992
Non-isotopic in situ hybridization of chromosome-specific alphoid DNA probes has become a potent tool in the study of numerical aberrations of specific human chromosomes at all stages of the cell cycle. In this paper, we describe approaches for the rapid

Karyotypic characterization of Hydromedusa tectifera (Testudines, Pleurodira) from the upper Iguaçu River in the Brazilian state of Paraná

open access: yesGenetics and Molecular Biology, 2006
We present the karyotypic characterization of 26 specimens of the side-necked turtle Hydromedusa tectifera collected in the upper Iguaçu River, Paraná state, Brazil.
