Chromosome number after a mitotic division
WebPrior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. WebDuring mitosis, chromosomes become attached to the structure known as the mitotic spindle. In the late 1800s, Theodor Boveri created the earliest detailed drawings of the spindle based on his...
