Question

Which amino acids are specified by the DNA code AATCATAGGACT?

Answer 1

use of genetic code

Explanation:

below is a figure for Genetic code

should have specified which orientation it is. usually it is the template strand whose peptide sequence is asked.

considering that this sequence is the DNA sequence in following orientation 3'-AAT-CAT-AGG-ACT-5' (TEMPLATE STRAND)

convert it into RNA
5'-UUA-GUA-UCC-UGA-3'

so your sequence will lead to
Leu-Val-Ser-stop.

alternate answer applicable only if the given strand is non-coding
5'-AAT-CAT-AGG-ACT-3'

convert to template strand
3'-TTA-GTA-TCC-TGA-5'

convert it to RNA
5'-AAU-CAU-AGG-ACU-3'

so your sequence will lead to
Asp-His-Arg-Thr
