These regions are shortened on each cell division and once they are gone, the cell cannot divide. Therefore an average cell in our body can divide only about 50 times. There are indications that longer telomeres may increase lifespan, however this remains controversial. farmers market west lothian

WebThe cells usually divide only once. Interface occurs prior to each division. Prophase division stage is relatively simple. The duration of prophase is short, usually a few hours.
