(20) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
Nucleolus
Definition:
(n.) A little nucleus.
(n.) A small rounded body contained in the nucleus of a cell or a protozoan.
Example Sentences:
