Ribonucleic acid required for rhizoid formation in Fucus zygotes is synthesized several hours before the production of proteins essential for this process. The period of synthesis of these proteins coincides with the irreversible commitment of a certain cytoplasmic region to initiate events leading to a visibly polar cell.
