ATGACCCAGATCATGAGG

ATGACCCAGATCATGAGG is an 18-nucleotide DNA sequence. It is commonly written as 5'-ATGACCCAGATCATGAGG-3'. In terms of base composition it contains six adenine (A), four cytosine (C), five guanine (G), and three thymine (T) residues.

In the standard coding orientation, the first reading frame yields the codons ATG ACC CAG ATC ATG AGG. This would translate to the amino acids Met-Thr-Gln-Ile-Met-Arg. When transcribed to mRNA, the sequence would be 5'-AUG ACC CAG AUC AUG AGG-3', producing the same amino acid sequence in that frame. Because the fragment is only 18 nucleotides long, it is not a complete gene by itself, and its biological role would depend on its larger genomic context and regulatory features.

Context and potential uses: Without additional information, the fragment has no inherent assigned function. It can be used as a synthetic oligonucleotide in molecular biology applications such as primer design, cloning, or DNA-protein interaction assays, depending on its intended purpose and the surrounding sequence. In nucleotide databases, this sequence would be catalogued as an 18-nt DNA fragment, with any functional interpretation requiring context from a larger gene or genomic region.
