Aug is the codon for methionine, and is also the start codon. Mutated trnas can be the cause of readthrough, but also certain nucleotide motifs close to the stop codon. Who can read these codes? A) the seqence will stop at gln, because uga is a stop codon. Codons in an mrna are read by a ribosome during translation. Uga, uaa, and uag are stop codons. Web stop codon suppression or translational readthrough occurs when in translation a stop codon is interpreted as a sense codon, that is, when a (standard) amino acid is 'encoded' by the stop codon. Web a stop codon is a sequence of three nucleotides (a trinucleotide) in dna or messenger rna (mrna) that signals a halt to protein synthesis in the cell. If uga, usually a stop codon, is found to code for an amino acid such as tryptophan (usually coded for by ugg only) a eukaryotic transcription unit that is 8,000 nucleotides long may use 1,200 nucleotides to make a protein consisting of approximately 400 amino acids. Web hence the secondary structure near the stop codon in the synthetic mrna may well differ from that in the natural mrna and possibly influence the likelihood of readthrough.

Web hence the secondary structure near the stop codon in the synthetic mrna may well differ from that in the natural mrna and possibly influence the likelihood of readthrough. Translational readthrough is very common in viruses and. Mutated trnas can be the cause of readthrough, but also certain nucleotide motifs close to the stop codon. 61 specify amino acids and 3 are stop codons (i.e., uaa, uag and uga). Web a stop codon is a sequence of three nucleotides (a trinucleotide) in dna or messenger rna (mrna) that signals a halt to protein synthesis in the cell. Three “stop” codons mark the end of a protein and terminate the translation. Web hence the secondary structure near the stop codon in the synthetic mrna may well differ from that in the natural mrna and possibly influence the likelihood of readthrough. Aug is the codon for methionine, and is also the start codon. There are 64 different trinucleotide codons: The three stop codons are nucleotide base triplets that play an important role in intracellular protein synthesis; A stop codon is a genetic code that signals the end of protein manufacturing inside the cell, like a period at the end of a sentence.
