**What does the production of three different polypeptides (polyserine, polyhistidine, and 
polyisoleucine) from an mRNA with repeating UCA synthesized by Khorana's group indicate?** 
 
**This result indicates that the genetic code is a triplet code.** 
 
**When Khorana's group synthesized an mRNA with repeating AGU, only polyserine (Ser) and 
polyvaline (Val) were produced. According to the codon table, why were only two po...
