Masked messenger RNA

In the late phases of embryogenesis there is also evidence of cytoplasmic determination of a number of differentiations by a similar mechanism of accumulation of long-living "masked messenger RNA in the cytoplasm and not functioning immediately after its formation. This has been shown, in particular, by the work of Kirk (1965), who studied the connection between RNA synthesis and synthesis of glutamine synthetase in the embryonic retina of chick embryos in vivo and in vitro Humphreys and co-workers (1964) discovered nonfunctional ribosomal aggregates in the skin of the...
