Answer 1

The complementary DNA sequence is 3'-ATGACTGACTGCTAG-5', the mRNA sequence is 5'-AUGACUGACUGCUAG-3', and the resulting amino acid sequence is Met-Thr-Asp-Thr-Ala.

Step-by-step explanation:

The first step is to construct the complementary DNA sequence. The complementary DNA sequence is formed by pairing each DNA base with its complementary base. In this case, the DNA sequence is: 5'-TACTGACTGACGATC-3'. The complementary DNA sequence would be: 3'-ATGACTGACTGCTAG-5'.

Next, to transcribe the template strand into mRNA, we replace thymine (T) with uracil (U). The mRNA sequence would be: 5'-AUGACUGACUGCUAG-3'.

Translating the mRNA using the genetic code, we can determine the resulting amino acid sequence. Each three-letter codon on the mRNA corresponds to a specific amino acid. Using the given genetic code, the resulting amino acid sequence would be: Met-Thr-Asp-Thr-Ala.
