WebIn eukaryotes, this stands for the amino acid methionine, and in bacteria, it stands for formylmethionine. The ribosome moves along the mRNA until it finds the start codon. Then, the ribosomal subunits come together around the mRNA. ... 2.tRNA Binding: During translation, small RNA molecules called transfer RNA (tRNA) that carry specific amino ... WebWhat is the tRNA for methionine? < I So now we realize that it is the transfer RNA that makes the magic-each RNA is linked to a spe- cific amino acid that is brought to the ribosome by base-pair bonding between the mRNA codon and the anticodon of the tRNA to which the amino acid is attached. the byward marketWebFeb 11, 2000 · It shows that translation of an insect viral RNA is initiated with glutamine and without the participation of the initiator methionine tRNA. A special RNA structure, including a pseudoknot involving nucleotides immediately upstream of the glutamine codon, is shown to be necessary for this exceptional mechanism of translation initiation. the byzantine empire gained the most brainly

"WebAlthough there is only one codon for methionine (AUG), there are two tRNAs for methionine in all organisms. One tRNA is used exclusively when AUG represents the initiation codon for protein synthesis. The second is used when methionine is added at an internal position in a polypeptide.
