Answer:
Cell cycle regulators
Explanation:
Cell division is important for an organism for growth, repair and replacement of cells and tissues. In the unfortunate event of uncontrolled cell division, the organism makes more cells than it can produce. Growing cells have four phases
G1: Growth by doubling of cytoplasm and organelles
S: Synthesis of new DNA and doubling of chromosome number
G2: A second round of growth to prepare for cell division
M: Cytokineses and the formation of two very identical cells
In an attempt to end the uncontrolled cell division one would first look into factors that initiate the G1 phase; stopping the growth of an out of control cell before it starts.
A second approach is to look into manipulating the check points at G2 and M. If there are drugs that can interfere at this point the cell will not divide uncontrollably and the potential cancer will be interrupted.
