kinetochore
The use of immunocytochemistry and immunoblotting methods revealed the presence of the specific kinetochore component, CENP A protein.
      
This suggests tight association of some molecular kinetochore components with chromocenters in the interphase.
      
We propose that meiotic restitution is a result of special genetic regulation of the kinetochore organization (both structural and functional) and chromatin condensation, i.e.
      
This suggests that these mutants are defective in some specific, but still unknown aspect of kinetochore-MT interaction.
      
Assembly of correct kinetochore architecture in Xenopus egg extract requires transition of sperm DNA through interphase
      
Our results indicate that the transition of sperm nuclei through interphase is an essential step for proper kinetochore assembly.
      
Irradiation of the kinetochore region of PtK2 chromosomes by laser light of 532 nm was used to study the function of the kinetochore region in chromosome movement and to create artificial micronuclei in cells.
      
The presence/absence of kinetochore(s) in a micronucleus is used as an indicator to determine the origin of the micronucleus.
      
The proportion of kinetochore-positive and kinetochore-negative micronuclei is used in the determination of the clastogenic and aneuploidogenic properties of different genotoxic agents.
      
The conditions required to yield such an equilibrium are a function of (1) the proportions of the various diploid restoring mechanisms (2) linkage to the kinetochore and (3) the intensity of selection.
      
Molecular-cytogenetic characterization of a higher plant centromere/kinetochore complex
      
In cells treated with OTA the fraction of kinetochore positive MN was similar (33-40%) to that observed in solvent controls (38%).
      
The mitotic kinetochore of the budding yeast contains a number of proteins which are required for chromosome transmission but are non-essential for vegetative growth.
      
However, chromosome segregation is often unequal, apparently due to a defect in kinetochore-microtubule interactions.
      
This and other genetic interactions between cofactor D mutants and specific kinetochore and spindle components suggest their critical role in establishing the normal kinetochore-microtubule interface.
      
For the centromere autoantibodies we found a high concordance between the anticentromere antibody (ACA) pattern on HEp-2 cells (27 patients positive) and the detection of recombinant kinetochore in immunoblotting (26 patients positive).
      
Using the immunoblotting technique with the recombinant antigens we detected in four patients antibodies against both Topo I and kinetochore.
      
The "pre-metaphase stretch" and kinetochore orientation in phasmids
      
The sex chromosomes of the male phasmid Isagoras schraderiRehn comprise an X and a Y, - each with a submedian kinetochore, and one euchromatic and one heterochromatic arm.
      
The r?le of the kinetochore in trivalent formation
