9. Looking at DNA changes more closely, use the If the DNA sequence is TAC, what will the RNA codon be? What amino acid and/or function does this RNA codon code for? What RNA codon(s) code for the amino acid arginine (ARG)? What RNA codon codes for tryptophan (TRP)? What was the DNA sequence that was transcribed to make this codon? (backwards transcribe it) If the last nucleotide (letter) in the TRP codon changes to a "U," will the amino...
