Verified
The main signaling cascade for cell division and differentiation is the ____ cascade.
A) cAMP
B) MAP kinase
C) phosphoinositol
D) phospholipase C
E) calcium-calmodulin
MAP Kinase
An enzyme that plays a critical role in signaling pathways, involved in cell processes like division, differentiation, and response to external stress.
Signaling Cascade
A series of biochemical events and reactions that occur within a cell in response to a signal, often involving activation of enzymes and resulting in a cellular response.

Final Answer :
B
Explanation :
The MAP kinase (mitogen-activated protein kinase) cascade is a crucial signaling pathway that regulates a wide range of cellular processes, including cell division and differentiation. This pathway transmits signals from receptors on the cell surface to the DNA in the nucleus, influencing gene expression and cell fate.
