Given a set of genomes g and a distance measure d, the genome rearrangement median problem asks for another genome q that minimizes Sigma n is an element of g(d(q,g)). This problem lies at the heart of phylogenetic reconstruction from rearrangement data. w ...
Vertebrate telomeres are transcribed into telomeric repeat-containing RNA (TERRA) that associates with telomeres and may be important for telomere function. Here, we demonstrate that telomeres are also transcribed in Saccharomyces cerevisiae by RNA polymer ...
A large variety of organisational forms for collaboration have emerged during the last years as a result of the many socio-economic challenges faced by the society and enabled by the new ICT developments. As a result, in both developed and developing count ...
The control of telomerase activity at chromosome ends by telomere-binding proteins is critical for telomere length homeostasis. Two recent papers identify TPP1 as a critical mediator of this control. TPP1 forms part of the telomeric shelterin complex while ...
Telomerase is the ribonucleoprotein enzyme that elongates telomeres to counteract telomere shortening. The core enzyme consists of a reverse transcriptase protein subunit and an RNA subunit. The RNA subunit contains a short region that is used as a templat ...
Telomeres, the DNA-protein complexes located at the end of linear eukaryotic chromosomes, are essential for chromosome stability. Until now, telomeres have been considered to be transcriptionally silent. We demonstrate that mammalian telomeres are transcri ...
Phosphorylation of H2AX (gamma H2AX) is an early sign of DNA damage induced by replication stalling. However, the role of H2AX in the repair of this type of DNA damage is still unclear. In this study, we used an inactivated adeno-associated virus (AAV) to ...
The 32 telomeres in the budding yeast genome cluster in three to seven perinuclear foci. Although individual telomeres and telomeric foci are in constant motion, preferential juxtaposition of some telomeres has been scored. To examine the principles that g ...
Even though a large variety of innovative façade technologies has been developed to refine the control of solar radiation and increase the amount of useful natural illumination, their effective implementation in buildings is still uncommon. Increasing the ...
Telomerase enables telomere length homeostasis, exhibiting increasing preference for telomeres as their lengths decline. This regulation involves telomere repeat-bound Rap1, which provides a length-dependent negative feedback mechanism, and the Tel1 and Me ...
