Answer:
A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.
Explanation:
Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.
Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
Earth's service would be bare. There would no longer be life and all water ways would become dried up due to the intense ultra-violent rays of the sun.
The proteins are produced in the golgi apparatus. Then, they are transported through the microtubules inside the cell towards the cell membrane. Then, the proteins pass through the lipid bilayer of the membrane. of the membrane and move out of the cell.
It also contains green pigment, in addition they contain various yellowish carotenoids the blue pigment, red pigment, brown, yellow and black pigments. That is what i think.
Chemically speaking, enzymes are composed of chains of amino acids, and they are considered to be a type of protein.
