MITOCHONDIA

most mitochondrial proteins are encoded by cellular nuclear genes and are synthesized on ribosomes before being transported into mitochondria. Only a few mitochondrial proteins are encoded by mtDNA and synthesized on the mitochondrial ribosome. This suggests that mitochondrial biosynthesis depends on two sets of genetic systems.

Semi-autonomy

① septal division

② Contraction division

③ Shoot division
