A new study suggests genetic changes allow horses to produce more energy, while minimizing the toll the energy takes on cells.

Hence, the resulting products provided clues that the researchers could use to deduce potential codon–amino acid relationships. For example, when A and C were mixed with polynucleotide ...

During that same year, Marshall Nirenberg and Heinrich Matthaei began deciphering the genetic code, and they determined that the codon UUU specifically represented the amino acid phenylalanine.
