Answer 1

The given DNA sequence codes for the primary amino acid sequence: Met-His-Gln-Leu-Stop.

Step-by-step explanation:

The given DNA sequence codes for the primary amino acid sequence: Met-His-Gln-Leu-Stop. This sequence corresponds to the mRNA sequence AUG-CAU-CAG-CUC-UAA. Using the codon chart, we can match each codon to its corresponding amino acid. The resulting amino acids are methionine (Met), histidine (His), glutamine (Gln), leucine (Leu), and a stop codon (Stop).
