For maximum stability, the donor pair (AH) and the acceptor (B) are usually colinear (that is, i., AHB = 180°), but deviations of up to 30° are known.

Sometimes the S1 nuclease will not digest the single stranded regions completely, so the transcript appears to be a little longer than it really is, But another method, called primer extension, can tell the 5’-end (but not the 3’-end) to the exact nucleotide

Autophagy occurs in the following sequence of steps:

Induction by activation of mTOR complex 1

• Nucleation of autophagosome formation by ATG9

• Closure of the membrane cup to form autophagosome

• Fusion of the autophagosome with lysosomes, catalyzed by SNAREs.

• Digestion of the inner membrane and the lumenal contents of the autophagosome
