Getting proteins into mitochondria from the cytoplasm is a remarkable process, and just creating and then dealing with the signal sequences involved seems to be a bit much to ask of mutation and selection acting all on their own.
Though the egg's chromosomes are divided equally between the two new cells, as before, almost all the cytoplasm is concentrated in one daughter cell, that which contains the sperm's nucleus.
Immediately inside the membrane is a fluid called the cytoplasm, which is filled with much of the complex chemical machinery necessary to the cell’s growth and function.
This means it can go to all parts of the cell, including the lipid (fat) portions such as the cell plasma membrane, as well as the interior of the cell (known as the cytoplasm) where water soluble chemicals reside.
What doctors is they take some of the cytoplasm, which is that jelly-like stuff around the nucleus.
Thus, the theory behind the IVF procedure known as cytoplasm transfer CT was born.
