Chromosomal radials
WebThe chromosomal DNA of eukaryotic species contains sequences called matrix-attachment regions (MARs) or scaffold-attachment regions (SARs), which are interspersed at regular intervals throughout the genome. The MARs bind to specific proteins in the nuclear matrix, thus forming chromosomal loops

Performing hitherto uninvestigated ultra-structural analysis of the human genome at prophase, we used serial block-face scanning electron microscopy (SBFSEM) to …
WebMay 4, 2004 · Radials were found to only involve non-homologous chromosome interactions and to be distributed nearly randomly along the length of chromosomes. Sites on chromosomes that did show increased frequency of radial involvement did not correlate with known fragile sites or pericentric regions. WebThe chromosomal DNA remains anchored to a scaffold, formed from the nuclear matrix. The chromosomes eventually become attached to the spindle apparatus via microtubules that attach to the kinetochore, which is attached to the centromere. Assume linker DNA averages 54 bp in length.
WebNov 8, 2024 · Interstrand crosslinks (ICLs) repair by the canonical Fanconi anemia (FA) pathway generates double-strand breaks (DSBs), which are subsequently repaired by the homologous recombination (HR) pathway. Recent studies show that the NEIL3 DNA glycosylase repairs psoralen-ICLs by direct unhooking.
WebWhen we examined chromosomal integrity by G-banding karyotype analyses, we found that targeted expression of satellite DNAs led to chromosomal breakage (Figure 2E, red arrows), chromosomal radials (Figure 2E, blue box), and translocations (Figure S3B).
