The megabase-scale crossover landscape is largely independent of sequence divergence
Nature Communications, 2022 The frequency of recombination varies along chromosomes and highly correlates with sequence divergence. Here, the authors show that polymorphisms are not a major determinant of the megabase-scale recombination landscape in Arabidopsis, which is rather ...

Chromosome Painting of Mouse Chromosomes [PDF]
, 2018 Chromosome painting enables the visualization of chromosomes and has been used extensively in cytogenetics. Chromosome paint probes, which consist of a pooled composite of DNA-FISH probes, bind to nonrepetitive sequences for individual chromosomes [1, 2].

Cell, 2002 In RNA-mediated interference (RNAi), double-stranded RNAs (dsRNAs) target complementary mRNAs for degradation. New work demonstrates that essential chromosomal functions are mediated through RNAi protein components and short RNAs, which alter chromosome function at specific DNA loci via histone modification.

PLOS Genetics, 2020 Holocentric chromosomes possess multiple kinetochores along their length rather than the single centromere typical of other chromosomes [1]. They have been described for the first time in cytogenetic experiments dating from 1935 and, since this first observation, the term holocentric chromosome has referred to chromosomes that: i.

The architecture of chicken chromosome territories changes during differentiation [PDF]
, 2004 BACKGROUND: Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory.

Chromosomal rearrangements in cattle and pigs revealed by chromosome microdissection and chromosome painting [PDF]
Genetics Selection Evolution, 2003 A pericentric inversion of chromosome 4 in a boar, as well as a case of (2q-;5p+) translocation mosaicism in a bull were analysed by chromosome painting using probes generated by conventional microdissection. For the porcine inversion, probes specific for p arms and q arms were produced and hybridised simultaneously on metaphases of a heterozygote ...

Architecture of metaphase chromosomes and chromosome scaffolds. [PDF]
The Journal of cell biology, 1983 We have developed procedures for depositing intact mitotic chromosomes and isolated residual scaffolds on electron microscope grids at controlled and reproducible levels of compaction. The chromosomes were isolated using a recently developed aqueous method. Our study has addressed two different aspects of chromosome structure.

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.
