Variant imprints displayed by the nucleotide base: Thymine. Note: The coronavirus genome uses RNA for encoding proteins, not DNA. The nucleotide base T is related to (U)racil in the nucleic acid RNA via three nucleotide bases, or mRNA codon. This allows to correlate symbols used for nucleic acids (polymers of nucleotides) to that of proteins (polymers of amino acids).
