We present a detailed analysis of the structure and assembly of ... ancestral loci predict that the rate of duplication among non-homologous chromosomes was at least three times higher with ...

This CENP-A centromere identifier attracts other proteins, and in cell division builds a massive structure, the kinetochore, for pulling the duplicated chromosomes apart during cell division.

In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a cellular machine composed of microtubules and their associated proteins. Spindles are built from ...

During mitosis, the parent cell will duplicate its chromosomes in order to pass ... are held together by a structure called the centromere. The sister chromatids then need to be evenly split ...

They are defined by their unusual structure: patchworks of blocks that are duplicated near the ends of multiple chromosomes. The maps of human subtelomeres are still sketchy, owing to the complex ...
