During translation in a eukaryotic cell
WebJun 8, 2024 · The eukaryotic pre-mRNA undergoes extensive processing before it is ready to be translated. The additional steps involved in eukaryotic mRNA maturation create a molecule with a much longer half-life than a prokaryotic mRNA. Eukaryotic mRNAs last for several hours, whereas the typical E. coli mRNA lasts no more than five seconds. WebA typical eukaryotic cell contains several types of spatially formed granules, such as P-bodies, stress granules and a variety of ribonucleoprotein bodies. These microdomains play important role in mRNA processing, including RNA interference, repression of translation and mRNA decay.

WebMay 17, 2024 · Transcription occurs within the nucleus of eukaryotes and translation occurs within the cytoplasm (Fig. 11.1 B). Prokaryotes do not have compartmentalization and have, thus, evolved a coupled trancription/translation system where both process occur simultaneously (Fig. 11.1 A). WebIn prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription is complete.
WebApr 9, 2024 · With the genes bound in a nucleus, the eukaryotic cell must be able to transport its mRNA to the cytoplasm and must protect its mRNA from degrading before it is translated. Eukaryotes also employ three different polymerases that each transcribe a … WebWithin all cells, the translation machinery resides within a specialized organelle called the ribosome.
