Question

Accepted Answer

### Part 1: Translating Codons (Using the Genetic Code Table)
#### Step 1: Translate AUC
- **Explanation**: Find the codon AUC. First letter A, second letter U, third letter C. From the table, A (first) - U (second) - C (third) corresponds to Ile (Isoleucine).
- **Expression**: AUC → Ile

#### Step 2: Translate ACC
- **Explanation**: Codon ACC. First letter A, second letter C, third letter C. A - C - C is in the Thr (Threonine) group (ACC is part of Thr's codons).
- **Expression**: ACC → Thr

#### Step 3: Translate CAU
- **Explanation**: Codon CAU. First letter C, second letter A, third letter U. C - A - U corresponds to His (Histidine).
- **Expression**: CAU → His

#### Step 4: Translate UGU
- **Explanation**: Codon UGU. First letter U, second letter G, third letter U. U - G - U is Cys (Cysteine).
- **Expression**: UGU → Cys

#### Step 5: Translate CAA
- **Explanation**: Codon CAA. First letter C, second letter A, third letter A. C - A - A is Gln (Glutamine).
- **Expression**: CAA → Gln

#### Step 6: Translate GCG
- **Explanation**: Codon GCG. First letter G, second letter C, third letter G. G - C - G is Ala (Alanine).
- **Expression**: GCG → Ala

### Part 2: Silent Mutation for CCU
#### Step 1: Recall Silent Mutation
- **Explanation**: A silent mutation changes the codon but not the amino acid. CCU codes for Pro (Proline). Find other codons for Pro.
- **Expression**: CCU (Pro) → Other Pro codons: CCC, CCA, CCG (since Pro's codons are CCU, CCC, CCA, CCG).

### Part 3: Genetics Cross Percentages
#### Step 1: Two carriers (Aa x Aa) for recessive disorder - child with disorder (aa)
- **Explanation**: Punnett square: Aa x Aa. Offspring: AA (25%), Aa (50%), aa (25%). So chance of aa (disorder) is 25%.
- **Expression**: 25% ✔️ (for "Two carriers...child with disorder")

#### Step 2: Two carriers (Aa x Aa) - child is carrier (Aa)
- **Explanation**: From Aa x Aa, Aa is 50% of offspring. So 50% chance.
- **Expression**: 50% ✔️ (for "Two carriers...child is carrier")

#### Step 3: PP x pp (flower color) - chance of white (pp)
- **Explanation**: PP x pp → all offspring Pp (purple). So white (pp) chance is 0%.
- **Expression**: 0% ✔️ (for "PP purple x pp white...white")

#### Step 4: PP x Pp (flower color) - chance of white (pp)
- **Explanation**: PP x Pp → offspring: PP (50%), Pp (50%). No pp, so white chance is 0%.
- **Expression**: 0% ✔️ (for "PP purple x Pp purple...white")

### Final Answers (Summarized)
- **Translations**: AUC→Ile, ACC→Thr, CAU→His; UGU→Cys, CAA→Gln, GCG→Ala
- **Silent Mutation for CCU**: CCC, CCA, or CCG (any one, e.g., CCC)
- **Cross Percentages**:
  - Two carriers (disorder child): 25%
  - Two carriers (carrier child): 50%
  - PP x pp (white): 0%
  - PP x Pp (white): 0%

(Note: For the table, mark the percentages as above. For the codon translation, the amino acids are Ile, Thr, His, Cys, Gln, Ala. For silent mutation, any of CCC/CCA/CCG is correct.)
