It proceeds via three steps: initiation, elongation and termination. proteins under a single control, mRNA with information for only one The key difference between prokaryotic and eukaryotic translation initiation is that prokaryotic translation initiation occurs on 70S ribosomes while eukaryotic translation initiation occurs on 80S ribosomes. Translation or protein synthesis is a process during which the genetic information is translated, following the dictations of the genetic code, into the sequence of amino acids in a polypeptide chain. Prokaryotic translation initiation takes place on 70s ribosomes, while eukaryotic translation initiation takes place on 80s ribosomes. low number of PTMs in comparison with eukaryotic proteins. The prokaryotes, which include bacteria and archaea, are mostly single-celled organisms that, by definition, lack membrane-bound nuclei and other organelles. In the process of translation, the nucleotide triplets, referred to as codons, present on the mRNA will be translated into an amino acid sequence. 2. Eukaryotic translation initiation factors use a three-step process to start translation. Difference # Prokaryotic Promoters: In prokaryotes, the promoter consists of two short sequences at -10 and -35 positions upstream from the transcription start site. Remarkably, more than 30 different polypeptides are involved in the initiation of translation in eukaryotes. prevents premature entry of tRNA to A site, IF2-GTP: helps in binding of fMEt What is the difference between prokaryotic and eukaryotic translation The IF1 factor is used in initiation to help to stabilize the 30S ribosomal subunit. Eukaryote organisms are multicellular which means they are made up of cells performing specialized functions. These factors do recognize three termination codes. In E. coli, the RNA polymerase has five subunits: two , one , one ' and one subunit ( 2 '). Translation or protein synthesis is a biological process that takes place in the cytoplasm.
