Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]
, 1977 When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

High‐Throughput Tiling of Essential mRNAs Increases Potency of Antisense Antibiotics
Advanced Science, EarlyView.The systematic tiling of essential genes’ mRNA here presented, proposes a valuable tool for the identification of novel PNA sequences with antibiotic potential. The high‐throughput synthetic set up opens the door to investigating thousands of sequences in an economic way and ultimately identifies potent antisense oligonucleotides while also giving room

Removal of antagonistic spindle forces can rescue metaphase spindle length and reduce chromosome segregation defects [PDF]
, 2012 Regular Abstracts - Tuesday Poster Presentations: no. 1925Metaphase describes a phase of mitosis where chromosomes are attached and oriented on the bipolar spindle for subsequent segregation at anaphase.

The dynamics of signal amplification by macromolecular assemblies for the control of chromosome segregation [PDF]
, 2014 The control of chromosome segregation relies on the spindle assembly checkpoint (SAC), a complex regulatory system that ensures the high fidelity of chromosome segregation in higher organisms by delaying the onset of anaphase until each chromosome is ...

Using Fluorescence Recovery After Photobleaching (FRAP) to study dynamics of the Structural Maintenance of Chromosome (SMC) complex in vivo [PDF]
arXiv, 2016 The SMC complex, MukBEF, is important for chromosome organization and segregation in Escherichia coli. Fluorescently tagged MukBEF forms distinct spots (or 'foci') in the cell, where it is thought to carry out most of its chromosome associated activities.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Prenatal and neonatal presentations of multiple congenital anomalies are difficult to diagnose and are associated with an increased risk of lethality. The differential diagnosis of antenatal presentations of radial ray malformations includes Fanconi anemia (FA), an inherited bone marrow failure disorder associated with congenital anomalies in ...

Mad2, Bub3, and Mps1 regulate chromosome segregation and mitotic synchrony in Giardia intestinalis, a binucleate protist lacking an anaphase-promoting complex. [PDF]
, 2014 The binucleate pathogen Giardia intestinalis is a highly divergent eukaryote with a semiopen mitosis, lacking an anaphase-promoting complex/cyclosome (APC/C) and many of the mitotic checkpoint complex (MCC) proteins.

Cohesins: Crossroad Between Cornelia de Lange Spectrum and Cancer Predisposition
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT The cohesin complex plays crucial roles in DNA repair, chromatid separation, and gene transcription regulation. Pathogenic variants in cohesins or dysfunctional transcriptional regulators lead to cohesinopathies, a broader group of disorders including Cornelia de Lange Spectrum (CdLSp), for which the prevalence of cancer cases remains unclear.

Confinement-induced glassy dynamics in a model for chromosome organization [PDF]
Phys. Rev. Lett. (2015) vol. 115, 198102, 2015 Recent experiments showing scaling of the intrachromosomal contact probability, $P(s)\sim s^{-1}$ with the genomic distance $s$, are interpreted to mean a self-similar fractal-like chromosome organization. However, scaling of $P(s)$ varies across organisms, requiring an explanation.
