# Synthetic DNA → Amino Acid ORF Translation Dataset
## 🧬 Summary
This dataset contains **synthetic DNA sequences** (`src`) and their corresponding **amino acid sequences** (`tgt`), where the label is defined as the **first valid ORF** from the 5' end:
> From the **first `ATG`** (start codon) encountered in the sequence
> to the **first in-frame stop codon** (`TAA`, `TAG`, or `TGA`) that follows it,
> translated into amino acids (excluding the stop).
The dataset is designed for training and evaluating models that learn **DNA→protein translation rules** and **ORF detection** in a slightly non-trivial, noisy setting.

## 📁 Dataset Structure
### Data fields
Each example is a JSON object with the following fields:
- `src` (string):
A DNA sequence (characters `A`, `C`, `G`, `T` only).
- Length is **variable**, from a minimum (e.g. 6 nt) up to a specified maximum.
- The sequence is mostly random, but guaranteed to contain at least one valid ORF.
- `tgt` (string):
The amino acid sequence translated from the ORF defined as:
- The first `ATG` found when scanning from the 5' end.
- The first **in-frame** stop codon (`TAA`, `TAG`, `TGA`) after that `ATG`.
- Translation uses the **standard genetic code**.
- The stop codon is **not included** in the amino acid string.
Example (conceptual):
```json
{
"src": "ACGTTGATGAAAACCGGGTAGTTCG...",
"tgt": "MKTVG"
}
