In its active GTP$-$bound form, the small G protein Ras binds to the serine$/$threonine kinase Raf$1,$ thereby recruiting Raf$1$ to the plasma membrane and inducing Raf$1$ activation. T cells that lack expression of RasGAP proteins spontaneously develop into T$-$cell leukemias. What would these cells show?

an absence of GDP$-$bound Rasincreased levels of activated Raf$1$reduced levels of Raf$1$ at the plasma membrane
