AUG has dual functions. It codes for Methionine (met), and it also act as initiator codon.
What are the three stop codons?
Each three-letter sequence of mRNA nucleotides corresponds to a specific amino acid, or to a stop codon. UGA, UAA, and UAG are stop codons.
Three codons, which do not encode for any amino acids, UAG (amber), UAA (ochre), and UGA (opal), are defined as stop codons
Is ATG a start codon?
The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome. ... The most common start codon is AUG (i.e., ATG in the corresponding DNA sequence).
Is TGA a stop codon?
In the standard bacterial codon table, there are three stop codons, TAG, TGA, and TAA (UAG, UGA, and UAA on mRNA)
Where are codons found?
mRNA
64 Codons constitute genetic code because
Genetic code is triplet.
