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. WebEukaryotic translation initiation factor 5A-1 (eIF5A) is an essential factor required for cell division in eukaryotes. eIF5A is activated through the hypusination of one specific Lys residue in its N-terminal domain. This posttranslational modification is mediated by the …

WebBy definition, eukaryotic cells are cells that contain a membrane-bound nucleus, a structural feature that is not present in bacterial or archaeal cells. In addition to the nucleus, eukaryotic cells are characterized by numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others. WebWith the genes enclosed 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 different subset of genes.
