In fact ribosomes join the nascent mRNA chain and engage in protein synthesis long before its transcription is complete. Provisions are even made for slowing down the ribo somes at some sites to prevent them from catching up with the RNA-polymerase. Of course such a situation is only possible in the prokaryotic world where there is no such thing as a nuclear mem brane physically secluding the transcription process from the cy toplasm where translation is restricted. Quite in the opposite extreme the eukaryotic pre-messenger RNA has to suffer many and sometimes drastic steps of maturation capping polyadenylation splicing edition before the decision is made to export it to the cytoplasm. That is where it enters the scope of this book. Once in the cytoplasm many options are still open to it: its entrance into polysomes may be delayed as it is in unfertilized eggs or merely prohibited ferritin mRNA in iron-starved cells directed to specific locations within the cytoplasm or be more or less rapidly degraded. During gametogenesis and early development translational control is probably the most significant level of gene expression.
