During wоund heаling, skin cells hаve different pаtterns оf grоwth and division depending on which stage of healing they are in. When a wound is still open (when there is a lack of cells in the center), cells have high levels of both growth and division. When the wound has just completely closed, growth slows but division continues. A. Describe how cells in these two different circumstances divide their time between different phases of the cell cycle (How is this different between the 2 cell populations?) B. What would be the most obvious outcome of repeated cell cycles consisting of S phase and M phase only? (What would these cells look like?)
