Biologist ___________________________ Codon Worksheet Date ____________ Use the circular codon table to complete the DNA triplets, mRNA codons, tRNA anticodons, and amino acids in the table below. DNA triplet TTC mRNA codon AAG GGC CCG GTC CAG AAU TTA AAA GTA UUU CAU CTC GAG ACA TGT TAT TCG ATT CCA GGC tRNA anticodon UUC GGC GUC UUA AAA GUA CUC Amino Acid lysine proline glutamine asparagine phenylalanine histidine UGU glutamic acid threonine AUA UAU isoleucine AGC UCG serine stop UAA GGU AUU CCA CCG GGC glycine proline Questions: 1. What 3 codons act as termination signals? UAG UAA UGA 2. What codon means start? AUG 3. List ALL of the codons for leucine. UUA UUG Name ALL the codons for these amino acids: 4. Phenylalanine – uuc uuu 5. Serine – ucu ucc uca ucg agu agc 6. Isoleucine – aua auc auu 7. Valine – gug guc guu gua 9. Glycine – ggu ggc gga ggg 10. Alanine – gcu gcc gc gcg 11. If the DNA sequence is --- AAA TAT CCG TAG CAA ATG, write the mRNA sequence, tRNA anticodon sequence, and the six amino acids for this. DNA: mRNA: tRNA: Amino acids: AAA TAT CCG TAG CAA ATG UUU AUA GGC AUC GUU UAC AAA UAU CCG UAG CAA AUG lysine tyrosine proline stop glutamine methionine
