Organization of Transcribed and Nontranscribed Chromatin [PDF]

open access: yes, 1980
In most eukaryotic nuclei two extreme forms of chromatin packing can be distinguished, condensed and dispersed chromatin. This does not exclude that, in addition, transitional or intermediate forms may exist. Ever since the pioneering morphological studies of Heitz (1929, 1932, 1956) cytologists have associated condensed chromatin, including the ...

Dynamics of subnuclear chromatin organization during "C. elegans" development : a role for H3K9 methylation [PDF]

open access: yes, 2012
In eukaryotic cells, DNA is packaged into chromatin. This imposes an accessibility barrier to all genetic processes, while at the same time offering the means for tight control.

The Structural Organization of Sperm Chromatin [PDF]

open access: yesJournal of Biological Chemistry, 2003
The packaging of the male haploid genome within the differentiating spermatid nucleus is facilitated by small basic nuclear proteins called protamines. Although the majority of the DNA in human sperm chromatin is bound by these proteins, a small percentage retains a nucleosomal-like component.

TRF2 controls telomeric nucleosome organization in a cell cycle phase-dependent manner [PDF]

open access: yes, 2012
Mammalian telomeres stabilize chromosome ends as a result of their assembly into a peculiar form of chromatin comprising a complex of non-histone proteins named shelterin.

Fission yeast condensin contributes to interphase chromatin organization and prevents transcription-coupled DNA damage

open access: yesGenome Biology, 2020
Background Structural maintenance of chromosomes (SMC) complexes are central organizers of chromatin architecture throughout the cell cycle. The SMC family member condensin is best known for establishing long-range chromatin interactions in mitosis ...

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]

open access: yes, 2004
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.

The role of nucleosome positioning in the evolution of gene regulation.

open access: yesPLoS Biology, 2010
Chromatin organization plays a major role in gene regulation and can affect the function and evolution of new transcriptional programs. However, it can be difficult to decipher the basis of changes in chromatin organization and their functional effect on

Perturbation of chromatin structure globally affects localization and recruitment of splicing factors [PDF]

open access: yes, 2012
Chromatin structure is an important factor in the functional coupling between transcription and mRNA processing, not only by regulating alternative splicing events, but also by contributing to exon recognition during constitutive splicing.

Pre-mRNA splicing is a determinant of nucleosome organization. [PDF]

open access: yesPLoS ONE, 2013
Chromatin organization affects alternative splicing and previous studies have shown that exons have increased nucleosome occupancy compared with their flanking introns. To determine whether alternative splicing affects chromatin organization we developed

The nuclear envelope as a chromatin organizer [PDF]

open access: yesNucleus, 2011
In the past 15 years our perception of nuclear envelope function has evolved perhaps nearly as much as the nuclear envelope itself evolved in the last 3 billion years. Historically viewed as little more than a diffusion barrier between the cytoplasm and the nucleoplasm, the nuclear envelope is now known to have roles in the cell cycle, cytoskeletal ...
