Let’s solve each codon step by step using the codon chart and codon wheel provided.

Part 1: Using the Codon Chart

The codon chart is organized like a grid:
- First letter (left side) → row
- Second letter (top) → column
- Third letter (right side of each box) → specific amino acid in that cell

We’ll go one by one:

1. CAG
- First letter C → find row starting with C
- Second letter A → go to column under A
- Third letter G → look at the 4th line in that box (since right side says U, C, A, G from top to bottom)
- In row C, column A, 4th entry = Glutamine

2. AUG
- Row A, column U, third letter G → 4th entry in that box
- Row A, column U: Isoleucine, Isoleucine, Isoleucine, Methionine → Methionine

3. CCU
- Row C, column C, third letter U → 1st entry
- Row C, column C: Proline, Proline, Proline, Proline → Proline

4. GGA
- Row G, column G, third letter A → 3rd entry
- Row G, column G: Glycine, Glycine, Glycine, Glycine → Glycine

5. UGA
- Row U, column G, third letter A → 3rd entry
- Row U, column G: Cysteine, Cysteine, Stop, Tryptophan → Stop

6. AGC
- Row A, column G, third letter C → 2nd entry
- Row A, column G: Serine, Serine, Arginine, Arginine → Serine

7. UCG
- Row U, column C, third letter G → 4th entry
- Row U, column C: Serine, Serine, Serine, Serine → Serine

8. CUA
- Row C, column U, third letter A → 3rd entry
- Row C, column U: Leucine, Leucine, Leucine, Leucine → Leucine

9. GUA
- Row G, column U, third letter A → 3rd entry
- Row G, column U: Valine, Valine, Valine, Valine → Valine

10. ACG
- Row A, column C, third letter G → 4th entry
- Row A, column C: Threonine, Threonine, Threonine, Threonine → Threonine

Part 2: Using the Codon Wheel

The codon wheel works from center outward:
- Inner circle = first base
- Middle ring = second base
- Outer ring = third base
- Then read the amino acid on the outermost layer

Let’s trace each:

1. AAU
- Start at center “A” → move to middle ring “A” → then outer ring “U”
- Points to Asparagine

2. CGA
- Center “C” → middle “G” → outer “A”
- Points to Arginine

3. GGA
- Center “G” → middle “G” → outer “A”
- Points to Glycine

4. UCU
- Center “U” → middle “C” → outer “U”
- Points to Serine

5. UGA
- Center “U” → middle “G” → outer “A”
- Points to Stop

6. GAC
- Center “G” → middle “A” → outer “C”
- Points to Aspartic acid

7. ACU
- Center “A” → middle “C” → outer “U”
- Points to Threonine

8. AGC
- Center “A” → middle “G” → outer “C”
- Points to Serine

9. CCA
- Center “C” → middle “C” → outer “A”
- Points to Proline

10. CGA (again)
- Same as #2 → Arginine

Final Answer:

Using the Codon Chart:
1. CAG = Glutamine
2. AUG = Methionine
3. CCU = Proline
4. GGA = Glycine
5. UGA = Stop
6. AGC = Serine
7. UCG = Serine
8. CUA = Leucine
9. GUA = Valine
10. ACG = Threonine

Using the Codon Wheel:
1. AAU = Asparagine
2. CGA = Arginine
3. GGA = Glycine
4. UCU = Serine
5. UGA = Stop
6. GAC = Aspartic acid
7. ACU = Threonine
8. AGC = Serine
9. CCA = Proline
10. CGA = Arginine
