Humans are blessed with five sensory organs such as eyes, ears, nose, tongue and skin which are influenced by the change in the environment.
Sensation refers to sensing the outer environment with the help of the sensory organs in the form of touch, smell, sound, taste and sight. According to the environmental conditions, the sensory organs act and send the message to the brain which is then interpreted. For example, change in the environmental temperature such as hot or cold is sensed by the skin and interpreted by the brain.
RAS is a very important protein that belongs to a class of protein referred to as GTPases and plays a crucial role in switching on pathways that control cell growth, proliferation, apoptosis and differentiation and migration. For RAS to become inactive it must hydrolyze GTP to GDP which slows down the process of cell proliferation. Mutation in one copies of RAS will result to cancer because the mutated copy will permanently attach to GTP and remain in activated form which will lead to uncontrollable cell division and hence development of cancer.
