DNA Protein sequence randomizer

This application supports IUPAC characters.
If you select the "Clean Sequence" option, every number, space, tab, slash or non-relevant character will be stripped out of from the input sequence

For details on IUPAC characters usage see here

RANDOMIZATION OPTIONS

Is your sequence ready, or do you need to remove unwanted characters? To clean or not to clean?

Clean and Randomize
Just Randomize

Select the number or randomization cycles

Number of randomization cycles

ALPHABET SELECTION

If the sequence needs cleaning, the selection of the correct alphabet is required
