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 ...

Scientists were able to identify chromosomes under the microscope as ... Thus, Flemming recognized that chromosomal movement during mitosis offered a mechanism for the precise distribution of ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Kinetochore capture by spindle microtubules and the subsequent chromosome movements occur via highly dynamic microtubules that maintain kinetochore attachment during significant microtubule turnover.

This principle can be used to explain and support different cell shapes and the movement of chromosomes during the subsequent phases. Examples of questions to ask students: How might the cytoskeleton ...
