Abstract:
The nature of the cytoplasmic RNA that appears to migrate along the optic path of the chick has been studied. A considerable proportion of retinally synthesized RNA contains a polyadenylic acid segment. A fraction of this presumptive messenger RNA moves distally to the optic tectum together with nonpolyadenylic acid-containing RNA. The poly(A)-containing and nonpoly(A)-containing RNA classes are transported in roughly the same proportions as their relative retinal cytoplasmic concentrations. The size of the poly(A) segments within the putative messenger RNA (mRNA) did not decrease with time. A proportion of nonmigrating mRNA in retina and optic tectum appeared to have considerable stability, as did transported mRNA.

pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
