Answer:
Through an anchor
Explanation;
-Protein Ras associates with the membranes through an anchor.
-Ras proteins are molecular switches that decide if and when cells divide inside our bodies, thus an impairment of their function may result in the formation of a tumor or cancer.
-Ras proteins require membrane association in order to be biologically active. Membrane anchorage of Ras proteins in the inner leaf- let of the plasma membrane is an important factor in their signaling and oncogenic potential.
