To determine the amino acid sequence produced from the given mRNA strand, we need to follow a detailed step-by-step process to decode the sequence according to the provided codon-to-amino acid mapping.
### Step 1: Identify and segment the mRNA strand
Given mRNA strand: `CAUGGUGGCUACGGG`
We will split this strand into individual codons (groups of three nucleotide bases each):
- CAU
- GGU
- GGC
- UAC
- GGG
### Step 2: Refer to the provided codon-to-amino acid mapping table
The table provided offers the necessary information to map each codon to its corresponding amino acid. Here is what the table shows:
| Amino Acids | Codons |
|-------------|------------------|
| Glycine | GGU, GGC, GGA, GGG |
| Histidine | CAU, CAC |
| Tyrosine | UAU, UAC |
### Step 3: Decode each codon
Using the table, map each of the codons from our split mRNA strand to their respective amino acids:
- CAU maps to Histidine
- GGU maps to Glycine
- GGC maps to Glycine
- UAC maps to Tyrosine
- GGG maps to Glycine
### Step 4: Sequence the amino acids together
The series of amino acids as decoded:
- Histidine
- Glycine
- Glycine
- Tyrosine
- Glycine
### Step 5: Formulate the answer
The amino acid sequence formed from the mRNA strand `CAUGGUGGCUACGGG` is:
- Histidine-Glycine-Glycine-Tyrosine-Glycine
### Step 6: Compare with the given options
From the provided options, we match our determined sequence:
- A. Glycine-histidine-glycine-glycine
- B. Glycine-histidine-histidine-tyrosine-histidine
- C. Histidine-glycine-glycine-glycine
- D. Histidine-glycine-glycine-tyrosine-glycine
The correct sequence is:
- D. Histidine-glycine-glycine-tyrosine-glycine
Hence, the correct answer is:
D. Histidine-glycine-glycine-tyrosine-glycine
