The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious ...

How are these unique sex chromosomes formed? "The sex of a somatic cell as highly differentiated as a neurone may be detected with no more elaborate equipment than a compound microscope following ...

This dilemma resonated with me given my background as a cell biologist. A decade earlier, my doctoral work had centered on trying to understand how chromosomes in normal cells are evenly distributed ...
