The three stop codons in mRNA are UAA, UAG, and UGA, where U stands for uracil, A for adenine, and G for guanine. Stop codons provide an end ... Jan 28, 2015 ... There are a further three on the complementary strand. Only one of these will translate to give the protein sequence, the others will not. The ... That means there are three codons that do not have corresponding tRNAs with complementary anticodons. These three codons serve as stop codons. When a ... ... three stop codons), in eukaryotes (2–4) (Fig. 1A). However, the mechanism of stop codon recognition by release factors is unknown and represents a long ... Of the 64 codons, three are stop codons, meaning only 61 codons code for an amino acid. ... Figure 3 shows two different codons that both code for the amino acid ... 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. ...
