Degeneracy of the genetic code and stability of the base pair at the second position of the anticodon. | LitMetric

With an analysis of the structural constraints of the anticodon-codon interaction within the decoding center of the ribosome, we show that the extent of degeneracy at the third position of the anticodon is determined by the level of stability of the base pair at the second position.
