Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]

, 2020
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Chromosome Segregation: Correcting Improperly Attached Chromosomes [PDF]

Current Biology, 2006
Two new studies show that Aurora B kinase corrects improperly attached chromosomes by recruiting molecules necessary for eliminating the bad attachments and by regulating the turnover of the kinetochore fiber.

A simple biophysical model emulates budding yeast chromosome condensation

eLife, 2015
Mitotic chromosomes were one of the first cell biological structures to be described, yet their molecular architecture remains poorly understood. We have devised a simple biophysical model of a 300 kb-long nucleosome chain, the size of a budding yeast ...

Segregation but Not Replication of the Pseudomonas aeruginosa Chromosome Terminates at Dif

mBio, 2018
Coordination between chromosome replication and segregation is essential for equal partitioning of genetic material between daughter cells. In bacteria, this is achieved through the proximity of the origin of replication, oriC, and the chromosome ...

A surge of late-occurring meiotic double-strand breaks rescues synapsis abnormalities in spermatocytes of mice with hypomorphic expression of SPO11 [PDF]

, 2015
Meiosis is the biological process that, after a cycle of DNA replication, halves the cellular chromosome complement, leading to the formation of haploid gametes.

Bacterial chromosome segregation.

Acta Biochimica Polonica, 2005
In most bacteria two vital processes of the cell cycle: DNA replication and chromosome segregation overlap temporally. The action of replication machinery in a fixed location in the cell leads to the duplication of oriC regions, their rapid separation to the opposite halves of the cell and the duplicated chromosomes gradually moving to the same ...

Kinetochore component function in C. elegans oocytes revealed by 4D tracking of holocentric chromosomes

Nature Communications, 2023
During cell division, chromosome congression to the spindle center, their orientation along the spindle long axis and alignment at the metaphase plate depend on interactions between spindle microtubules and kinetochores, and are pre-requisite for ...
