Eukaryotes process
WebApr 28, 2024 · Eukaryotes are organisms whose bodies are made up of eukaryotic cells, such as protists, fungi, plants and animals. Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms with eukaryotic cells are grouped into the biological domain Eukaryota (also sometimes called Eukarya). WebAll eukaryotes have or belong to lineages that once had mitochondria, an endosymbiotic organelle derived from an alpha proteobacterium. These organelles have been lost, reduced, or converted to fermentative, hydrogenproducing organelles (hydrogenosomes) multiple times ( Dyall and Johnson 2000; Martin, Chapter 5, this volume).

In the capping step of mRNA processing, a methylated-guanosine (7-methyl-G) is linked to the phosphates at the 5' end of the mRNA. The cap protects the 5' end of the mRNA from degradation by nucleases and also helps to position the mRNA correctly on the ribosomes during protein synthesis. Figure 2.2. 2: The mRNA capping structure is a ...
