well, now you are basically down to the classical quetsion: what was first?
the hen or the egg?
what happens during cell division is that the two daughter cells each get
approximately half of the ribosomes from the mother cell, and therefore the
cell are already equipped with the necessary tools for protein synthesis
from "birth". Therefore the "old" ribosomes will make ribosomal proetins for
During fertilization the zygote (the new cell) will almost only get the DNA
from the sperm cell, and the rest (i.e. also ribosomes) will come from the
mothers egg cell.
