or sausage-like organelles capable of undergoing rounds of fusion
and fission.

the observation of reticulartype
morphologies has been restricted to mitochondrial mutants
or to cells subjected to experimental perturbations.

Although
mitochondria contain their own DNA, mtDNA, and can synthesize
proteins, they are only semi-autonomous organelles, since most of
