Hip hop music, also called hip-hop or rap music, is a music genre formed in the United States in the 1970s that consists of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching, break dancing, and graffiti writing. Other elements include sampling (or synthesis), and beatboxing.
While often used to refer to rapping, "hip hop" more properly denotes the practice of the entire subculture. The term hip hop music is sometimes used synonymously with the term rap music, though rapping is not a required component of hip hop music; the genre may also incorporate other elements of hip hop culture, including DJing, turntablism, and scratching, beatboxing, and instrumental tracks.
Rap GTP-binding protein also known as Ras-related proteins or simply RAP is a type of small GTPase, similar in structure to Ras.
These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. RAP counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner.
Human genes that encode Ras-related proteins include:

Afrique 50 is a 1956 French documentary film directed by René Vautier. The first French anti-colonialist film, the film derived from an assignment in which the director was to cover educational activities by the French League of Schooling in West Africa. Vautier later filmed what he saw, a "lack of teachers and doctors, the crimes committed by the French Army in the name of France, the instrumentalization of the colonized peoples". For his role in the film Vautier was imprisoned over several months. The film was not permitted to be shown for more than 40 years.
