WebIn eukaryotes, apart from catalyzing the translation termination reaction, eRF1 binds to and activates another factor, eRF3, which is a ribosome-dependent and eRF1-dependent GTPase. Because peptidyl-tRNA hydrolysis and GTP hydrolysis could be uncoupled in vitro, we suggest that the two main functions of eRF1 are associated with different domains of the … WebThree stages of transcription. Initiation ; Elongation ; Termination Three-nucleotide groups that specify the amino acids sequence of a polypeptide are called? codons In bacteria, a short sequence in the mRNA provides a location the recruits the machinery to start translation. The sequence is called? ribosome-binding site The terminator is?
