If the following mRNA strand were produced during transcription, what amino acids would be found in the protein?

CAUGGUGGCUACGGG

Use the table below to determine the amino acids:

| Amino Acids | Glycine | Histidine | Tyrosine |
|-------------|---------|-----------|----------|
| Codons | GGU | CAU | UAU |
| | GGC | CAC | UAC |
| | GGA | | |
| | GGG | | |

A. Histidine-glycine-glycine-glycine
B. Glycine-histidine-glycine-glycine
C. Glycine-histidine-histidine-tyrosine-histidine
D. Histidine-glycine-glycine-tyrosine-glycine



Answer :

To determine the amino acids that would be found in the protein coded by the given mRNA strand CAUGGUGGCUACGGG, we need to follow a few steps:

1. Identify Codons: Break the mRNA strand into codons, which are groups of three nucleotides. The given mRNA strand can be divided as follows:
- CAU
- GGU
- GGC
- UAC
- GGG

2. Translate Codons to Amino Acids: Using the codon table provided, we translate each codon into its respective amino acid. Here's how it translates:
- CAU -> Histidine
- GGU -> Glycine
- GGC -> Glycine
- UAC -> Tyrosine
- GGG -> Glycine

3. Combine the Amino Acids: The sequence of amino acids according to the codons will be:
- Histidine
- Glycine
- Glycine
- Tyrosine
- Glycine

Therefore, the amino acid sequence corresponding to the mRNA strand CAUGGUGGCUACGGG is:

Histidine-Glycine-Glycine-Tyrosine-Glycine

Hence, the correct answer is:

D. Histidine-glycine-glycine-tyrosine-glycine
