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.

Alexander Varshavsky discovered, the half-lives of many cytoplasmic proteins vary with the identities of their N-terminal residues via the so-called N-end rule:-
| 
			 A. Destabilizing N-terminal residues Asp, Arg, Leu, Lys, and Phe have half-lives of  | 
			
			 i. Only 2 to 3 minutes,  | 
		
| 
			 B. Stabilizing N-terminal residues Ala, Gly, Met, Ser, Thr, and Val have half-lives of  | 
			
			 ii. >10 hours in prokaryotes iii. >20 hours in eukaryotes.  |
