CHO chromosomes, prepared for fluorescence microscopy, or for scanning electron microscopy, sometimes show a splitting of the centromere proper into two sister centromeres, with a space between them, while the sister chromatids are joined in the most proximal regions of the chromosome arms. It is su

โฆ Synopsis
The mammalian centromere is a multifunctional chromosomal domain with a complexity that is reflected in its higher order structure, DNA sequence organization and protein composition. The centromere plays a major role during cell division where it functions as the site for the integration of the chromosome with the mitotic spindle, the site of the mechanochemical motor responsible for the movement of chromosomes and the major and last point of interaction between sister chromatids. Recent studies have focused on characterizing the components of the centromere and establishing their relationship to its function. The following brief review summarizes some selected aspects of this recent work.

Some of the proposals are for more of the same, where the 'same' under reference is to something that is known to be effective and to work well. Th
Two reports have shown that mammalian artificial chromosomes (MAC) can be constructed from cloned human centromere DNA and telomere repeats, proving the principle that chromosomes can form from naked DNA molecules transfected into human cells. The MACs were mitotically stable, low copy number and bo
