WebHow do eukaryotic codons and prokaryotic codons compare? A) Prokaryotic codons usually specify different amino acids than those of eukaryotes. B) The translation of codons is mediated by tRNAs in eukaryotes, but translation requires no intermediate molecules such as tRNAs in prokaryotes. WebThe reason that the genetic code can correctly specify the order of amino acids in a polypeptide is specific tRNAs become attached to specific amino acids. A characteristic shared by eukaryotic mRNA, tRNA, and …
WebIn eukaryotes like humans, the main RNA polymerase in your cells does not attach directly to promoters like bacterial RNA polymerase. Instead, helper proteins called basal ( general) transcription factors bind to the promoter first, helping the RNA polymerase in your cells get a foothold on the DNA. WebSmall subunit matches tRNAs to mRNA codons; large subunit catalyzes formation of peptide bonds o Two subunits come together on mRNA near 5’ end; mRNA pulled through and moves forward in 5’-3’ direction o After protein is synthesized, two subunits are separated o Eukaryotic ribosome adds 2 AA’s per second; prokaryotic 20 AA’s/sec …
