To decode the given mRNA sequence "GAU" and find the corresponding amino acid, we follow these steps:
1. Identify the Sequence: The mRNA sequence provided is composed of three nucleotides: guanine (G), adenine (A), and uracil (U).
2. Match the Codon: We need to determine which amino acid corresponds to the codon "GAU".
3. Use a Codon Chart: Use a codon chart to find the amino acid that corresponds to the codon "GAU". In a standard codon chart, the codon "GAU" is associated with a specific amino acid.
Here is a simplified example of how the codon chart might look like (not complete):
[tex]\[
\begin{array}{|c|c|c|c|c|}
\hline
\text{First Base} & U & C & A & G \\
\hline
\text{Second Base} & & & & \\
\hline
\text{Third Base} & & & & \\
\hline
U & \text{Phe, Leu} & \text{Ser} & \text{Tyr, Stop} & \text{Cys, Trp} \\
C & \text{Leu} & \text{Pro} & \text{His, Gln} & \text{Arg} \\
A & \text{Ile, Met} & \text{Thr} & \text{Asn, Lys} & \text{Ser, Arg} \\
G & \text{Val} & \text{Ala} & \text{Asp, Glu} & \text{Gly} \\
\hline
\end{array}
\][/tex]
4. Locate the Codon "GAU" on the Chart:
- Within the chart, navigate to the row and column that corresponds to the bases G (first position of the codon), A (second position of the codon), and U (third position of the codon).
5. Find the Amino Acid:
- The codon "GAU" translates to the amino acid "Aspartic acid" or abbreviated as "Asp".
### Final Answer:
The amino acid that corresponds to the mRNA codon sequence "GAU" is "Aspartic acid" (Asp).
