Final answer:
The mRNA codon GCA corresponds to the amino acid alanine in protein synthesis.
Step-by-step explanation:
Using the mRNA Codon Chart, the codon GCA codes for the amino acid alanine (Ala). It is important to note that in mRNA, the nucleotides are adenine (A), uracil (U), guanine (G), and cytosine (C). Hence, the RNA sequence GCA would pair with the tRNA anticodon CGU, which would carry the amino acid alanine. In protein synthesis, the process of translating an mRNA sequence into an amino acid sequence involves reading the mRNA codons and using tRNA to add the corresponding amino acids to the growing polypeptide chain.
The codon GCA codes for the amino acid arginine.
