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?
Although mitosis and meiosis both involve cell division, they transmit genetic material in very different ways. What happens when either of these processes goes awry?
Scientists were able to identify chromosomes under the microscope as early as the 19th century. But what did it take for them to figure out how important chromosomes really are?
Cells duplicate and condense their DNA prior to entering mitosis. During mitosis, chromosomes attach to a spindle of microtubules that distribute them equally to two daughter cells.
