Chromosome cohesion: A polymerase for chromosome bridges [PDF]
Current Biology, 2000 How do cells ensure that sister chromatids produced during DNA replication stay connected with each other until their separation in anaphase? New insight is provided by the discovery of DNA polymerase kappa, which has been found to be required for building the connections between sister chromatids.

Frontiers in Genetics, 2018 The study of patterns and evolutionary processes in neotropical fish is not always an easy task due the wide distribution of major fish groups in large and extensive river basins. Thus, it is not always possible to detect or correlate possible effects of

The chromosomes of the Filariae [PDF]
Filaria Journal, 2005 An understanding of the nature of the chromosomes of the filariae is expected to greatly assist the future interpretation of genome data. Filarial development is not eutelic, and there does not seem to be a fixed number of cell divisions in the way that there is in Caenorhabditis.

Chromosome Oscillations in Mitosis [PDF]
, 2005 Successful cell division requires a tight regulation of chromosome motion via the activity of molecular motors. Many of the key players at the origin of the forces generating the movement have been identified, but their spatial and temporal organization remains elusive.

Role of the Number of Microtubules in Chromosome Segregation during Cell Division [PDF]
PLoS ONE 10(10): e0141305 (2015), 2015 Faithful segregation of genetic material during cell division requires alignment of chromosomes between two spindle poles and attachment of their kinetochores to each of the poles. Failure of these complex dynamical processes leads to chromosomal instability (CIN), a characteristic feature of several diseases including cancer.

The chromosomal organization of horizontal gene transfer in bacteria
Nature Communications, 2017 Bacterial adaptation is accelerated by the acquisition of novel traits through horizontal gene transfer, but the integration of these genes affects genome organization.

Meiosis: the chromosomal foundation of reproduction
Biology of Reproduction, 2018 Meiosis is the chromosomal foundation of reproduction, with errors in this important process leading to aneuploidy and/or infertility. In this review celebrating the 50th anniversary of the founding of the Society for the Study of Reproduction, the ...
