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

[tex] \text{GGCUACGGGCAUCAC} [/tex]

The table below shows which amino acid results from each codon.

\begin{tabular}{|r|ccc|}
\hline
Amino acids & Glycine & Histidine & Tyrosine \\
\hline
Codons & GGU & CAU & UAU \\
& GGC & CAC & UAC \\
& GGA & & \\
& GGG & & \\
\hline
\end{tabular}

A. Histidine-glycine-glycine-glycine-tyrosine

B. Glycine-tyrosine-glycine-histidine-histidine

C. Glycine-glycine-tyrosine-glycine-histidine

D. Histidine-glycine-glycine-tyrosine-glycine

To determine the sequence of amino acids produced from a given mRNA strand, we should break the strand into codons (groups of three bases) and use the provided codon table to translate each codon into its corresponding amino acid.

The mRNA strand given is:

GGCUACGGGCAUCAC

We will break it into codons as follows:
1. GGC
2. UAC
3. GGG
4. CAU
5. CAC

Next, we will translate each codon using the given codon to amino acid mappings:

1. GGC - This codon corresponds to Glycine.
2. UAC - This codon corresponds to Tyrosine.
3. GGG - This codon corresponds to Glycine.
4. CAU - This codon corresponds to Histidine.
5. CAC - This codon corresponds to Histidine.

Putting it all together, the sequence of amino acids is:

Glycine, Tyrosine, Glycine, Histidine, Histidine

Therefore, the correct answer is:

B. Glycine-tyrosine-glycine-histidine-histidine
