Question

write the amino acid using its three - letter abbreviation. write stop for a stop codon.
dna sequence
mrna codon gca
amino acid
submit

Explanation:

Step1: Determine the DNA sequence

Since mRNA is transcribed from DNA, and the base - pairing rules are A - U, T - A, C - G, G - C. For the mRNA codon GCA, the DNA sequence (template strand) is CGT.

Step2: Find the amino acid

Using the standard genetic code, the mRNA codon GCA codes for the amino acid alanine. The three - letter abbreviation for alanine is Ala.

Answer:

DNA sequence: CGT; Amino acid: Ala
