The onset of homologous chromosome pairing during Drosophila melanogaster embryogenesis. [PDF]
, 1993 We have determined the position within the nucleus of homologous sites of the histone gene cluster in Drosophila melanogaster using in situ hybridization and high-resolution, three-dimensional wide field fluorescence microscopy.

Chromosome segregation in plant meiosis [PDF]
, 2014 Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

California Agriculture, 1982 Not available – first paragraph follows: Success in hybridizing wild with cultivated species ultimately depends on the ability of the alien chromosomes to pair and recombine with the chromosomes of the crop species at meiosis.

Management of E. coli sister chromatid cohesion in response to genotoxic stress
Nature Communications, 2017 Homologous recombination of DNA lesions in bacteria involves sister chromatid pairing. Here, the authors show that RecN promotes contacts between sister chromatids and facilitates repair.

Sequence analysis of wheat subtelomeres reveals a high polymorphism among homoeologous chromosomes
The Plant Genome, 2020 Bread wheat, Triticum aestivum L., is one of the most important crops in the world. Understanding its genome organization (allohexaploid; AABBDD; 2n = 6x = 42) is essential for geneticists and plant breeders. Particularly, the knowledge of how homologous

Mechanics and dynamics of X-chromosome pairing at X inactivation. [PDF]
PLoS Computational Biology, 2008 At the onset of X-chromosome inactivation, the vital process whereby female mammalian cells equalize X products with respect to males, the X chromosomes are colocalized along their Xic (X-inactivation center) regions.

Invariants for Lagrangian tori
, 2004 We define an simple invariant of an embedded nullhomologous Lagrangian torus and use this invariant to show that many symplectic 4-manifolds have infinitely many pairwise symplectically inequivalent nullhomologous Lagrangian tori.

Centromeric SMC1 promotes centromere clustering and stabilizes meiotic homolog pairing.
PLoS Genetics, 2019 During meiosis, each chromosome must selectively pair and synapse with its own unique homolog to enable crossover formation and subsequent segregation.

Computational identification and analysis of noncoding RNAs - Unearthing the buried treasures in the genome [PDF]
, 2007 The central dogma of molecular biology states that the genetic information flows from DNA to RNA to protein. This dogma has exerted a substantial influence on our understanding of the genetic activities in the cells.

TurboFold: Iterative probabilistic estimation of secondary structures for multiple RNA sequences
BMC Bioinformatics, 2011 Background The prediction of secondary structure, i.e. the set of canonical base pairs between nucleotides, is a first step in developing an understanding of the function of an RNA sequence.
