Window Extractor DNA
Window Extractor DNA accepts a DNA sequence along with a window position and window size. The bases corresponding to the window are returned, either as a new sequence, as uppercase text, or as lowercase text. Use Window Extractor DNA to obtain subsequences using position information.

Paste a raw sequence or one or more FASTA sequences into the text area below. Input limit is 500000 characters.

Extract a window of size position
Please check the browser compatibility page before using this program.
  • Obtain bases from the strand.
  • Sequence windows should be returned as
