Eukaryotic mrna processing
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. WebTranslation is the process by which the genetic information carried by mRNA is used to synthesize a protein. In eukaryotes, translation occurs in the cytoplasm and involves …

However, that doesn't mean transcription is the last chance for regulation. Later stages of gene expression can also be regulated, including: RNA processing, such as splicing, capping, and poly-A tail addition

http://pressbooks-dev.oer.hawaii.edu/biology/chapter/rna-processing-in-eukaryotes/ WebMar 6, 2024 · In eukaryotic cells, RNA synthesis, which occurs in the nucleus, is separated from the protein synthesis machinery, which is in the cytoplasm. The initial product of transcription of an mRNA is sometimes referred to as the pre-mRNA. After it has been processed and is ready to be exported from the nucleus, it is called the mature mRNA.
WebThe 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.
WebJun 8, 2024 · Eukaryotic mRNAs last for several hours, whereas the typical E. coli mRNA lasts no more than five seconds.
