Allelic segregation and independent assortment in T. brucei crosses: proof that the genetic system is Mendelian and involves meiosis [PDF]
, 2005 The genetic system on Trypanosoma brucei has been analysed by generating large numbers of independent progeny clones from two crosses, one between two cloned isolates of Trypanosoma brucei brucei and one between cloned isolates of T. b.

Chromosome segregation in lymphocyte hybrids [PDF]
Hereditas, 2009 Chromosome segregation was studied in mouse/human and mouse/mouse T-lymphocyte hybrids, and in mouse/human, mouse/rabbit and mouse/rat B-lymphocyte hybrids. Chromosome loss was not random, it was moderate in mouse/mouse and mouse/rat lymphocyte hybrids, but extensive in mouse/human and mouse/rabbit lymphocyte hybrids.

The role of chromosome segregation and nuclear organisation in human subfertility [PDF]
, 2019 Spermatogenesis is central to successful sexual reproduction, producing large numbers of haploid motile male gametes. Throughout this process, a series of equational and reductional chromosome segregation precedes radical repackaging of the haploid ...

Chromosomal macrodomains and associated proteins : implications for DNA organization and replication in gram negative bacteria [PDF]
, 2011 The Escherichia coli chromosome is organized into four macrodomains, the function and organisation of which are poorly understood. In this review we focus on the MatP, SeqA, and SlmA proteins that have recently been identified as the first examples of ...

Cdc14 and PP2A Phosphatases Cooperate to Shape Phosphoproteome Dynamics during Mitotic Exit
Cell Reports, 2019 Summary: Temporal control over protein phosphorylation and dephosphorylation is crucial for accurate chromosome segregation and for completion of the cell division cycle during exit from mitosis. In budding yeast, the Cdc14 phosphatase is thought to be a

SMC is recruited to oriC by ParB and promotes chromosome segregation in Streptococcus pneumoniae [PDF]
, 2011 Segregation of replicated chromosomes is an essential process in all organisms. How bacteria, such as the oval-shaped human pathogen Streptococcus pneumoniae, efficiently segregate their chromosomes is poorly understood.

On the origin of crossover interference : a chromosome oscillatory movement (COM) model [PDF]
, 2011 Background: It is now nearly a century since it was first discovered that crossovers between homologous parental chromosomes, originating at the Prophase stage of Meiosis I, are not randomly placed.

Double-checking chromosome segregation
Journal of Cell Biology, 2023 Enduring chromosome segregation errors represent potential threats to genomic stability due to eventual chromosome copy number alterations (aneuploidy) and formation of micronuclei—key intermediates of a rapid mutational process known as chromothripsis that is found in cancer and congenital disorders.

Nuclear Organization and Chromosome Segregation [PDF]
The Plant Cell, 1999 The genetic information underlying plant form and function is contained within the cell nucleus in the form of complex, dynamic DNA–protein structures—the chromosomes. The faithful transmission of these structures during mitosis and meiosis requires extensive chromosome reorganization and ...

Both Chromosome Decondensation and Condensation Are Dependent on DNA Replication in C.elegans Embryos [PDF]
, 2015 During cell division, chromatin alternates between a condensed state to facilitate chromosome segregation and a decondensed form when DNA replicates.
