Class 1 release factor

WebIn prokaryotes, two class 1 release factors, RF1 and RF2, decode UAA/UAG and UAA/UGA stop codons, respectively. In Eukaryotes, a single release factor, eRF1, recognizes all three stop codons in eukaryotes. So, option B is correct and option C is incorrect. D. The Shine-Dalgarno sequence is the ribosomal binding site in bacterial and archaeal ... Eukaryotic translation termination factor 1 (eRF1), also known as TB3-1, is a protein that in humans is encoded by the ETF1 gene. In eukaryotes and archaea, this is the sole class 1 release factor (eRF) which recognizes all three stop codons. The overall process of termination is similar in bacteria, but in the latter 2 separate codon-recognizing release factors exist, …
