Purified mRNA encoding horse globin could direct globin synthesis in a tulip cell. Which property of the genetic code does that show?

1. A tulip cell reading a horse transcript correctly means both organisms assign the same amino acid to the same triplet. 2. Virtually all species use the same genetic code for protein synthesis, which is what universality states. 3. Degeneracy is about several triplets sharing one amino acid, which this transfer does not test. 4. Colinearity is about triplets matching amino acids in consecutive order within one message. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 15 "Genes and Proteins", section 15.1 The Genetic Code_
