The advantages of seeing a specialist vs a primary care physician is that the specialist knows exactly about that field of medicine. One circumstance for a specialist: Your eye is bleeding and red, you might want to go see an ophthalmologist because they focus on the eyes. One circumstance for a primary care physician: You feel weak, dizzy and you are vomiting, you have no specific area of pain, so you might want to see a primary care physician because they know about different fields of medicine instead of just focusing on one.
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.
