Select true ‘T’ AND false ‘F’ about ubiquitinylation
I. These ubiquitin-like modifiers control processes as diverse as nuclear import,
II. Regulated by the ubiquitin-like modifier Sumo, and autophagy,
III. Regulated by the ubiquitin-like modifier Atg8.
IV. For a protein to be efficiently degraded, it must be linked to a chain of at least four tandemly linked ubiquitin molecules in which Lys 34 of each ubiquitin forms an isopeptide bond with the C-terminal carboxyl group of the following ubiquitin.

Following statements are regarding to the phosphoinositide pathway.
A. many activated RTKs and cytokine receptors initiate phosphoinositide pathway by recruiting the enzyme phosphatidylinositol-3 kinase (PI-3 kinase) to the membrane.
B. PI-3 kinase adds a phosphate to the 3′ carbon in one of two separate phosphatidylinositol substrates, leading to formation of two phosphatidylinositol 3-phosphates: PI(3,4)P2 or I(3,4,5)P3
C. PI-3 kinase pathway can trigger cell division and prevent apoptosis, thus ensuring cell survival by the activation of PKB.
D. Activated PKB phosphorylates FOXO3a, which induces the expression of several antiapoptotic genes.
