The correct sequence of the first six amino acids in HbA beta globulin peptide is

Options

A. Valine - Histidine - Leucine - Threonine - Proline - Glutamic acid
B. Valine - Histidine - Leucine - Proline - Glutamic acid - Threonine
C. Leucine - Valine - Histidine - Threonine - Proline - Glutamic acid
D. Valine - Histidine - Leucine - Threonine - Proline - Valine

Answer

To determine the correct sequence of the first six amino acids in the HbA beta globulin peptide, we can follow these steps:

### Step 1: Identify the Codons
We start by identifying the codons that correspond to the amino acids in the beta globulin peptide. The transcript mentions the following codons:
- GUG
- CAC
- CUG
- ACU
- CCG
- GAG

### Step 2: Translate Codons to Amino Acids
Next, we translate each codon into its corresponding amino acid:
1. **GUG** - Valine (Val)
2. **CAC** - Histidine (His)
3. **CUG** - Leucine (Leu)
4. **ACU** - Threonine (Thr)
5. **CCG** - Proline (Pro)
6. **GAG** - Glutamic Acid (Glu)

### Step 3: Write the Sequence
Now that we have translated the codons, we can write the sequence of the first six amino acids:
- Valine
- Histidine
- Leucine
- Threonine
- Proline
- Glutamic Acid

### Step 4: Confirm the Sequence
Finally, we confirm that the sequence is correct based on the information provided in the transcript. The sequence of amino acids is:
1. Valine
2. Histidine
3. Leucine
4. Threonine
5. Proline
6. Glutamic Acid

### Final Answer
The correct sequence of the first six amino acids in HbA beta globulin peptide is:
**Valine - Histidine - Leucine - Threonine - Proline - Glutamic Acid**
