vortexxyynubb/GenomeConsole ? reverse-engineered prompt

Build me a simple full stack DNA sequence analyzer that lets someone paste a DNA sequence or upload a FASTA, GenBank, or plain text file and then explore the results in a clean web app.

I want the app to validate the sequence automatically, show basic stats like length and GC content, and then have easy tabs or panels for reverse complement, transcription to RNA, translation to protein, ORF finding, restriction enzyme analysis, motif search, pairwise alignment, mutation comparison, and an online BLAST lookup. If an uploaded file has more than one sequence, let the user pick which record to load. Show helpful error messages for bad sequences instead of crashing.

Please make it as a React frontend with a Python FastAPI backend, with the backend doing the actual biology logic and file parsing. Keep the API neat and make the frontend talk to it in one place. It should run locally with separate frontend and backend servers, and on Windows it would be great if a single batch file can start everything. Look up current docs online if you need to.
