Codon Worksheet with circular codon table for translating genetic code into amino acids.

Let’s solve this step by step.

We are given a circular codon table and need to fill in a table with:
- DNA triplets (template strand)
- mRNA codons
- tRNA anticodons
- Amino acids

But wait — the actual table below the codon wheel is blurred out. We can’t see what values are already filled in or what we’re supposed to complete.

However, since this is a standard “Codon Worksheet” task, I’ll assume you’re being asked to practice converting between DNA → mRNA → tRNA → amino acid using the codon chart.

Let me walk you through how to do one example from scratch so you can apply it to your worksheet.

---

Step 1: Start with a DNA triplet (template strand).
Example: Let’s say the DNA triplet is TAC

Step 2: Find the complementary mRNA codon.
Remember: In transcription, DNA template pairs with mRNA like this:
A ↔ U
T ↔ A
C ↔ G
G ↔ C

So for DNA TAC → mRNA is AUG

Step 3: Use the codon wheel to find the amino acid for mRNA AUG.
Look at the center of the wheel: first letter = A
Then middle ring: U
Then outer ring: G
That points to Methionine (also the start codon)

Step 4: Find the tRNA anticodon.
tRNA anticodon is complementary to mRNA codon.
mRNA: AUG → tRNA: UAC

(Recall: tRNA uses U instead of T, and base-pairs with mRNA: A↔U, U↔A, G↔C, C↔G)

Let’s try another one:

DNA: AAA
→ mRNA: UUU (because A in DNA pairs with U in mRNA)
→ Look up UUU on codon wheel: First U, then U, then U → Phenylalanine
→ tRNA anticodon: AAA (complementary to UUU)

Another:

DNA: CGT
→ mRNA: GCA
→ Codon wheel: G → C → A → Alanine
→ tRNA: CGU

One more:

DNA: ATT
→ mRNA: UAA
→ Codon wheel: U → A → A → Stop (no amino acid — termination signal)
→ tRNA: none (stop codons don’t have tRNA)

---

Now, if your worksheet has specific rows to fill in, just follow these steps for each row:

1. If given DNA → make mRNA (replace T with U, complement bases)
2. Use mRNA to look up amino acid on codon wheel
3. Make tRNA anticodon (complement of mRNA, use U not T)
4. If given amino acid → work backwards using codon wheel to find possible mRNA codons, then get DNA and tRNA

Note: Some amino acids have multiple codons — pick any one unless specified.

Also remember: The DNA shown is usually the *template* strand (the one RNA polymerase reads), NOT the coding strand.

Final Answer:
Since the actual table in your image is blurred and no specific entries are visible, here’s a completed sample row based on common worksheet problems:

| DNA Triplet | mRNA Codon | tRNA Anticodon | Amino Acid |
|-------------|------------|----------------|----------------|
| TAC | AUG | UAC | Methionine |
| AAA | UUU | AAA | Phenylalanine |
| CGT | GCA | CGU | Alanine |
| ATT | UAA | — | Stop |

Use this method to fill in your own worksheet. For each row, match the given value (whether it’s DNA, mRNA, tRNA, or amino acid) and use the rules above to find the others. Always double-check with the codon wheel!
