WebJul 1, 2024 · The most widely used identification of a eukaryotic cell is the presence of a nucleus. The main job of the nucleus is to house the DNA, or genetic information, of the cell. In a prokaryote, the DNA is just found in the cytoplasm, usually in a single ring shape. 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 …
