Chromosome cohesion: A polymerase for chromosome bridges [PDF]
Current Biology, 2000 How do cells ensure that sister chromatids produced during DNA replication stay connected with each other until their separation in anaphase? New insight is provided by the discovery of DNA polymerase kappa, which has been found to be required for building the connections between sister chromatids.

Numerous Transitions of Sex Chromosomes in Diptera
PLoS Biology, 2015 Many species groups, including mammals and many insects, determine sex using heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila melanogaster, generally have XY sex chromosomes and a conserved karyotype consisting of six ...

The chromosomes of the Filariae [PDF]
Filaria Journal, 2005 An understanding of the nature of the chromosomes of the filariae is expected to greatly assist the future interpretation of genome data. Filarial development is not eutelic, and there does not seem to be a fixed number of cell divisions in the way that there is in Caenorhabditis.

A method for nucleic acid hybridization to isolated chromosomes in suspension [PDF]
, 1987 A procedure was developed to provide differential fluorescent staining of metaphase chromosomes in suspension following nucleic acid hybridization. For this purpose metaphase chromosomes were isolated from a Chinese hamster x human hybrid cell line ...

Mammalian Y chromosomes retain widely expressed dosage-sensitive regulators
Nature, 2014 The human X and Y chromosomes evolved from an ordinary pair of autosomes, but millions of years ago genetic decay ravaged the Y chromosome, and only three per cent of its ancestral genes survived. We reconstructed the evolution of the Y chromosome across

Biochemical evidence of chromosome homoeology among related plant genera. [PDF]
, 1975 Biochemical markers associated with homoelogous chromosome groups 3 and 7 of Triticum aestivum L. have been investigated in genetic stocks carrying chromosomes or chromosomal segments of the same homoeology groups from Agropyron elongatum and Secale ...

Anchoring linkage groups of the Rosa genetic map to physical chromosomes with tyramide-FISH and EST-SNP markers [PDF]
, 2014 In order to anchor Rosa linkage groups to physical chromosomes, a combination of the Tyramide-FISH technology and the modern molecular marker system based on High Resolution Melting (HRM) is an efficient approach.

The first case of bilateral gynandromorphic plumage type in the bearded reedling Panurus biarmicus
The European Zoological Journal, 2023 Bilateral gynandromorphism is a condition in which an individual has both male and female phenotypes distributed symmetrically on the body. We describe the first case of a likely gynandromorphic bearded tit, which was trapped in Poland.
