Genetic Diversity on the Sex Chromosomes

open access: yesGenome Biology and Evolution, 2018
Levels and patterns of genetic diversity can provide insights into a population’s history. In species with sex chromosomes, differences between genomic regions with unique inheritance patterns can be used to distinguish between different sets of possible

Rapid generation of chromosome-specific alphoid DNA probes using the polymerase chain reaction [PDF]

open access: yes, 1992
Non-isotopic in situ hybridization of chromosome-specific alphoid DNA probes has become a potent tool in the study of numerical aberrations of specific human chromosomes at all stages of the cell cycle. In this paper, we describe approaches for the rapid

Chromosome Structure: Coiling up chromosomes [PDF]

open access: yesCurrent Biology, 1995
The mechanism by which eukaryotic chromosomes condense as cells enter mitosis has long been inaccessible to molecular biologists. An important clue has now been provided by a ubiquitous protein family, the SMCs.

A dynamic mode of mitotic bookmarking by transcription factors. [PDF]

open access: yes, 2016
During mitosis, transcription is shut off, chromatin condenses, and most transcription factors (TFs) are reported to be excluded from chromosomes. How do daughter cells re-establish the original transcription program? Recent discoveries that a select set

The chromosomes of the Filariae [PDF]

open access: yesFilaria 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.

Chromosome instability in Alzheimer’s disease [PDF]

open access: yesArchives of Biological Sciences, 2011
Alzheimer’s disease (AD), as the most common form of dementia, has for many years attracted the attention of researchers around the world, primarily because of the problems of reliable diagnostic methods that could help in the early detection of this ...

DNA methylation profiling of human chromosomes 6, 20 and 22

open access: yesNature Genetics, 2006
DNA methylation is the most stable type of epigenetic modification modulating the transcriptional plasticity of mammalian genomes. Using bisulfite DNA sequencing, we report high-resolution methylation profiles of human chromosomes 6, 20 and 22, providing

A fragmented metazoan organellar genome [PDF]

open access: yes, 2008
Background: Animal mitochondrial (mt) genomes are characteristically circular molecules of ~16–20 kb. Medusozoa (Cnidaria excluding Anthozoa) are exceptional in that their mt genomes are linear and sometimes subdivided into two to presumably four ...

Chromosome cohesion: A polymerase for chromosome bridges [PDF]

open access: yesCurrent 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.
