Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]

open access: yes, 1984
In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

Architecture of metaphase chromosomes and chromosome scaffolds. [PDF]

open access: yesThe Journal of cell biology, 1983
We have developed procedures for depositing intact mitotic chromosomes and isolated residual scaffolds on electron microscope grids at controlled and reproducible levels of compaction. The chromosomes were isolated using a recently developed aqueous method. Our study has addressed two different aspects of chromosome structure.

Induction of chromosome shattering by ultraviolet light and caffeine [PDF]

open access: yes, 1981
Synchronized and asynchronously growing cells of a V79 sub-line of the Chinese hamster were either partial-cell irradiation (λ, 254 nm) or laser-UV-microirradiated (λ, 257 nm).

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

Mathematical modelling of whole chromosome replication [PDF]

open access: yes, 2010
All chromosomes must be completely replicated prior to cell division, a requirement that demands the activation of a sufficient number of appropriately distributed DNA replication origins.

Early events in the evolution of the Silene latifolia Y chromosome: Male specialization and recombination arrest [PDF]

open access: yes, 2007
Understanding the origin and evolution of sex chromosomes requires studying recently evolved X-Y chromosome systems such as those in some flowering plants.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids

open access: yes, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

The MatP/matS Site-Specific System Organizes the Terminus Region of the E. coli Chromosome into a Macrodomain [PDF]

open access: yes, 2008
The organization of the Escherichia coli chromosome into insulated macrodomains influences the segregation of sister chromatids and the mobility of chromosomal DNA.

Induction of chromosome shattering by ultraviolet light and caffeine: The influence of different distributions of photolesions [PDF]

open access: yes, 1986
Cells of synchonized and of asynchronously growing cultures of a V79 Chinese hamster line were microirradiated with a low poweer laser-UV-microbeam of wavelength 257 nm.
