Given the DNA template strand 3' GTCGAACGT 5', write the amino acid sequence in the N- terminal to C- terminal direction. Use the three‑letter amino acid abbreviations (for example, Glu‑Asp‑Val). First, write the complementary mRNA sequence, matching each base of the DNA strand with its complementary RNA base. Use the genetic code to determine which amino acid each three base codon specifies.

Answer:

The complementary mRNA is 3' CAGCUUGCA 5' and the amino acid is Gln-Leu-Ala.

Explanation:

The complementary mRNA sequence is obtained by assigning the complementary base for each DNA base, in this case, thymines are changed for uracils because it is RNA. Then, with the genetic code, each triplet codifies for one amino acid, in this case CAG codifies for Gln and that way the other ones are obtained.
