The pairs of chromosomes that have been replicated are called sister chromatids, and they remain joined at a central point called the centromere. A large structure called the mitotic spindle also ...

Michael Lampson, PhD is a cell biologist at the University of Pennsylvania. His research group focuses on cell division, centromere function in the germline, and the cell biology of meiotic drive.

Researchers propose a two-step regulatory mechanism for non-Rabl configurations of centromeres in the nucleus. Centromeres are chromosomal domains that link pairs of sister chromatids together during ...

are highly condensed and still attached to one another at a point called the centromere. Human chromosomes can be differentiated from one another under a microscope by their lengths and by the ...
