Mitotic Antipairing of Homologous Chromosomes
2022Chromosome organization is highly dynamic and plays an essential role during cell function. It was recently found that pairs of the homologous chromosomes are continuously separated at mitosis and display a haploid (1n) chromosome set, or "antipairing," organization in human cells. Here, we provide an introduction to the current knowledge of homologous

Homologous chromosome pairing in wheat
Journal of Cell Science, 1999ABSTRACT Bread wheat is a hexaploid (AABBDD, 2n=6x=42) containing three related ancestral genomes, each having 7 chromosomes, giving 42 chromosomes in diploid cells. During meiosis true homologues are correctly associated in wild-type wheat, but a degree of association of related chromosomes (homoeologues) occurs in a mutant (ph1b).

Homologous chromosome recognition via nonspecific interactions
2023AbstractIn many organisms, most notablyDrosophila, homologous chromosomes in somatic cells associate with each other, a phenomenon known as somatic homolog pairing. Unlike in meiosis, where homology is read out at the level of DNA sequence complementarity, somatic homolog pairing takes place without double strand breaks or strand invasion, thus ...

Do homologous chromosomes differ?
Cytogenetic and Genome Research, 1979This paper is concerned with the problem of deciding whether measurements from homologous chromosomes differ. First, a general mathematical model is proposed for studying the distribution of chromosome measurements. Next, log-likelihood ratios are used to test for correlation between homolog pairs and for differences between homolog means and variances.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1977
Commonly accepted precepts are challenged : (1) that homologous chromosome pairing is normally mediated by nuclear envelope attachment sites; (2) that crossover site establishment awaits synaptic completion; and (3) that it is the function of the synaptonemal complex to hold homologues in register so that equal crossing over can occur, and perhaps to ...

Homologous Recombination Using Bacterial Artificial Chromosomes
Cold Spring Harbor Protocols, 2015This protocol introduces the technique of homologous recombination in bacteria to insert a linear DNA fragment into bacterial artificial chromosomes (BACs). Homologous recombination allows the modification of large DNA molecules, in contrast with conventional restriction endonuclease-based strategies, which cleave large DNAs into numerous fragments and

Human chromosome 9 pericentric homologies: implications for chromosome 9 heteromorphisms
Cytogenetic and Genome Research, 1998Pericentromeric polymorphisms of chromosome 9 include variations in the size of heterochromatin, pericentric inversions, and, more rarely, additional C-band-negative, G-band-positive material in either the proximal short arm or long arm or within the heterochromatin.

Chimpanzee chromosome 12 is homologous to human chromosome arm 2q
Cytogenetic and Genome Research, 1978Most of the 46 human chromosomes find their counterparts in the 48 chimpanzee chromosomes except for chromosome 2 which has been hypothesized to have been derived from a centric fusion of two chimpanzee acrocentric chromosomes. These two chromosomes correspond to the human chromosomes 2p and 2g.
