Mitochondria also possess a small genome that encodes genes whose functions are typically restricted to the mitochondrion.
Mitochondria having its own genome supports the theory that they were once aerobic bacteria that got engulfed by a host cell. #ithink
Microtubules help the cell resist compression, provide a track along which vesicles move through the cell, pull replicated chromosomes to opposite ends of a dividing cell,
So microfilaments aid in cell movement, intermediate filaments aid in structural support, and microtubules aid in both cell movement and structural support. #ithink
To solve this problem, those cells often have significantly more mitochondria than cells that do not require such a large constant energy supply.
So cells are able to create more mitochondria according to energy needs? I thought that the number of mitochondria is dictated by the cell's DNA.
