FAQ
Are the answers ever wrong?
Answers are computed by code and independently checked by two methods. A teacher should review the activity before use.
Do Biology tools use AI credits?
No. Biology tools are pure code — they work with one click and never use a generation credit.
Where does the genetic code come from?
The standard genetic code is fetched from NCBI (transl_table=1) and stored as versioned static data with its source shown on every sheet that uses it.
