Webb30 mars 2016 · Ribosomes can stall during protein synthesis on truncated or damaged mRNAs that lack a stop codon. In bacteria, these “non-stop” ribosomes are rescued by trans -translation or by an alternative rescue factor, ArfA or ArfB. Most eukaryotes do not have trans -translation, but mammals have a homolog of ArfB named ICT1. cody animeWebbThe biological machine that reads mRNA and pieces together amino acids is called a ribosome, and every cell has thousands (bacteria) to millions (some mammalian cells) of them.
