A Model of DNA Repeat-Assembled Mitotic Chromosomal Skeleton
Despite intensive investigation for decades, the principle of higher-order organization of mitotic chromosomes is unclear. Here, I describe a novel model that emphasizes a critical role of interactions of homologous DNA repeats (repetitive elements; repetitive sequences) in mitotic chromosome architecture. According to the model, DNA repeats are assembled, via repeat interactions (pairing), int...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Expandable DNA Repeat and Human Hereditary Disorders
Background & Aims: Nearly 30 hereditary disorders in humans result from an increase in the number of copies of simple repeats in genomic DNA, including fragile X syndrome, myotonic dystrophy, Huntington’s disease, and Friedreich’s ataxia. One the most frequently occurring types of mutation is trinucleotide repeat expansion. The present study was conducted with the aim of investigating the cause...
متن کاملThe mitotic origin of chromosomal instability
chromosomes, with only 2–6% anaphase CIN-cells displaying lagging chromosomes compared to 12–17% anaphase CIN+ cells (Figure 1B). CIN+ cells also contained multiple lagging chromosomes per anaphase, whereas multiple lagging chromosomes were rarely observed in CIN-cells (not shown). Very few acentric fragments were observed in anaphase for both CIN-and CIN+ cells, and this result was also confir...
متن کاملSubnuclear relocalization and silencing of a chromosomal region by an ectopic ribosomal DNA repeat.
Our research addresses the relationship between subnuclear localization and gene expression in fission yeast. We observed the relocalization of a heterochromatic region, the mating-type region, from its natural location at the spindle-pole body to the immediate vicinity of the nucleolus. Relocalization occurred in response to a DNA rearrangement replacing a boundary element (IR-R) with a riboso...
