CodonLab TEXT-ANALYSIS SANDBOX
Paste a raw sequence, get transcription and translation instantly.
NCBI / NUCLEOTIDE LOOKUP
Find a sequence, then analyze it
Search NCBI records and import a selected nucleotide sequence into the CodonLab analysis pipeline.
NCBI data are public records. CodonLab uses NCBI E-utilities for live lookup; imported sequences are analyzed locally in this session.
Sequence input TYPE
0 / 1,000,000
DNA / RNA sequence input. RNA U bases are normalized for nucleotide analysis.
