A Codon for the Amino Acid Serine Undergoes a Transversion

question 19

Short Answer

A codon for the amino acid serine undergoes a transversion so that it now codes for threonine. A transversion at a different site in the same codon then suppresses the first mutation. Give the nucleotides in the original codon, the transition mutation, and the transversion suppressor. (Note: There are two possible answers.)
