(d) Interactions between cyclins and cyclin-dependent kinases control
the cell cycle. Explain how the presence or absence of inhibitors of
cyclin-dependent kinases might play a role in normal cells becoming
cancer cells.
(d) Interactions between cyclins and cyclin-dependent kinases control
the cell cycle. Explain how the presence or absence of inhibitors of
cyclin-dependent kinases might play a role in normal cells becoming
cancer cells.
Cyclin dependent kinases play a major role in regulating cell cycle and
progression of the cell from one cell cycle stage to the next. In a normal
cell, in the presence of inhibitors of cyclin-dependent kinases the cell
cycle stops or the progression of the cell cycle is delayed. The G1 phase
where the cell cycle arrest happens is due to inhibitors (CDI).
The absence of inhibitors will increase cell proliferation and less number
of cell will be seen in the G1 stage.
So in the absence of inhibitors there will not be cell regulation but
uncontrolled cell proliferation which will push the normal cells to
behave like cancer cells. Inhibitors of cyclin dependent kinases are now
being used in the treatment of cancer cells as well, as they will help in
arresting the cell cycle and prevent their division and spread to other
tissues.
, (c) Neurons (nerve cells) of the central nervous system (brain and spinal
cord) are in G0 of the cell cycle and generally do not divide in response
to an injury. The scientists predict that they can use the data from this
experiment to help them treat individuals who suffer from spinal cord
injuries. Provide reasoning to support the scientists' prediction.

The data here would provide the crucial information on which protein is
required to induce the cells to enter the cell cycle. To recover from an
injury the cells should divide and repair the wound, this will happen
through stimulating the cell with the required protein. It would also shed
light on which protein would inhibit the cells from entry into the cell
