DNA probably. It might be one of the latter rungs too, thymine, and 2 others I forgot

This is the law of dominance in genetics. The dominant allele will mask the effects of the
recessive allele and therefore will be the visible trait of the phenotype. Most often, the dominant allele codes for functional proteins, while the recessive does not code for functional proteins. Dominance in genetics is
significant in Mendelian inheritance.
