Webb19 apr. 2024 · Remarkably, the most frequent location of the first EEJs is just preceding the main translation initiation codon. These results are consistent with the metagene plots centered at the initiation codon (Figure 1B, right panel). Strikingly, these EEJ distribution patterns are similar across the five species examined. WebbATG or AUG. The codon for Methionine; the translation initiation codon. Usually, protein translation can only start at a Methionine codon (although this codon may be found elsewhere within the protein sequence as well ). In eukaryotic DNA, the sequence is ATG; in RNA it is AUG. Usually, the first AUG in the m RNA is the point at which ...

WebbThe region of a nucleotide that starts from an initiation codon and ends with a stop codon is called an Open Reading Frame(ORF). An initiation codon is the triplet codon that codes for the first amino acid in the translation process. The translation process will start only with the initiation codon, ATG which codes for the amino acid methionine. WebbThe start codon is the initial set of codons in an mRNA transcript that is translated by a ribosome. In eukaryotes, the most common start codon is AUG which codes for …
