You are interested in how CAMP-dependent protein kinase A (PKA) functions to affect learning and memory, and you decide to study its function in the brain. It is known that, in the cells you are studying, PKA is an effecter protein of a GPCR signaling pathway that stimulates adenylyl cyclase. Iit is also known that activated PKA phosphorylates the transcriptional regulator called Nerd that then activated transcription of the gene Brainy.

Violence

Violence is defined as a physical act that causes or is intended to cause harm. Violence can cause physical, emotional, or both types of harm. Violence is defined by the World Health Organization as the intended use of physical force and power that causes threat or harm against oneself, another person, or against a community or group, and has the potential to cause damage, death, mental distress, maldevelopment, or poverty.
