Centromeres
Also known as... The terms ‘centromere’ and ‘kinetochore’ are often used synonymously but it is best to consider the centromere as the DNA and chromatin on which the kinetochore is assembled and the kinetochore as the protein machine, including centromeric chromatin, which mediates attachment to the spindle. Centromeres are found near the centre of the chromosome on metacentric chromosomes, but...
متن کاملNon-Repetitive Tilings
In 1906 Axel Thue showed how to construct an infinite non-repetitive (or squarefree) word on an alphabet of size 3. Since then this result has been rediscovered many times and extended in many ways. We present a two-dimensional version of this result. We show how to construct a rectangular tiling of the plane using 5 symbols which has the property that lines of tiles which are horizontal, verti...
متن کاملCentromeres
Centromeres, chromosomal regions that become physically linked to the spindle during cell division, ensure equal division of genetic material between daughter cells. They are ubiquitous and essential in eukaryotic life. In this primer, we ask the questions 'What defines a functional centromere?' and 'What do all centromeres have in common?' To address these questions we highlight what is known ...
متن کاملHACS: Heuristic Algorithm for Clustering Subsets
The term consideration set is used in marketing to refer to the set of items a customer thought about purchasing before making a choice. While consideration sets are not directly observable, finding common ones is useful for market segmentation and choice prediction. We approach the problem of inducing common consideration sets as a clustering problem on the space of possible item subsets. Our ...
متن کاملA conserved repetitive DNA element located in the centromeres of cereal chromosomes.
Repetitive DNA sequences have been demonstrated to play an important role for centromere function of eukaryotic chromosomes, including those from fission yeast, Drosophila melanogaster, and humans. Here we report on the isolation of a repetitive DNA element located in the centromeric regions of cereal chromosomes. A 745-bp repetitive DNA clone pSau3A9, was isolated from sorghum (Sorghum bicolor...
