Chromosomal aberrations in transitional cell carcinoma that are predictive of disease outcome are independent of polyploidy [PDF]
Objective To determine whether aneusomy for chromosomes 7, 9 and 17 (reported to predict recurrence in up to 65% of patients with superficial transitional cell bladder cancer and thus providing the opportunity for early and effective treatment) reflects ...

Chromosome Structure: Coiling up chromosomes [PDF]
The mechanism by which eukaryotic chromosomes condense as cells enter mitosis has long been inaccessible to molecular biologists. An important clue has now been provided by a ubiquitous protein family, the SMCs.

Disease-associated patterns of disomic chromosomes in hyperhaploid neoplasms.
The chromosome number of human tumors varies widely, from near-haploidy to more than decaploidy. Overt hyperhaploid (24-34 chromosomes) tumors constitute a small minority (0.2-0.3% of cytogenetically investigated lesions), but occur in many different ...

Early events in the evolution of the Silene latifolia Y chromosome: Male specialization and recombination arrest [PDF]
Understanding the origin and evolution of sex chromosomes requires studying recently evolved X-Y chromosome systems such as those in some flowering plants.

Chromosomics: Bridging the Gap between Genomes and Chromosomes [PDF]
The recent advances in DNA sequencing technology are enabling a rapid increase in the number of genomes being sequenced. However, many fundamental questions in genome biology remain unanswered, because sequence data alone is unable to provide insight into how the genome is organised into chromosomes, the position and interaction of those chromosomes in

Molecular cytotaxonomy of primates by chromosomal in situ suppression hybridization [PDF]
A new strategy for analyzing chromosomal evolution in primates is presented using chromosomal in situ suppression (CISS) hybridization. Biotin-labeled DNA libraries from flow-sorted human chromosomes are hybridized to chromosome preparations of ...

Chromosome Evolution: The Junction of Mammalian Chromosomes in the Formation of Mouse Chromosome 10 [PDF]
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.

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.

Cytogenetic analysis of five Hypostomus species (Siluriformes, Loricariidae)
In this work, we analyzed the karyotypes of five species. Hypostomus cf. heraldoi, from the Mogi-Guaçu River, had 2n = 72 chromosomes, with a nucleolar organizer region (NOR) in one chromosomal pair.
