# GlobalChem DNA

GlobalChem has the concept of a DNA into a 1-Dimensional format that can be used later on for dna-smiles to dna-ligand interaction of lexical strings. This way we can perhaps make casual inference between sets of ligands and sets of dna or proteins later on. 

**Import the Package**

```
from global_chem_extensions import GlobalChemExtensions
bioinformatics = GlobalChemExtensions().bioinformatics()
```

**Initialize a DNA Object**

```
dna_molecule = bioinformatics.initialize_globalchem_dna(
        peptide_sequence='TGGGGAGGGTG',
)
```

**Convert to SMILES**
