As the building-blocks for the organelle, production of rRNA is ultimately the rate-limiting step in the synthesis of a ribosome. In the nucleolus, rRNA is synthesized by RNA polymerase I using the specialty genes (rDNA) that encode for it, which are found repeatedly throughout the genome. The genes coding for 18S, 28S and 5.8S rRNA are located in the nucleolus organizer region and are transcribed into large precursor rRNA (pre-rRNA) molecules by RNA polymerase I. These pre-r… churchill arms kensington thaiWeb14 dec. 2024 · Another difference between a DNA and RNA vaccine is that a DNA vaccine delivers the message via a small electrical pulse, which “literally pushes the message into the cell,” Cifuentes-Kottkamp says. “The advantage is that this vaccine is very stable at higher temperatures.
