Silent Mutator - Silent mutagenesis tool

A gene synthesis tool, with which you can easily introduce new restriction sites without changing the amino acid / protein sequence.

The genetic code used for translation of the input sequence is selected from the dropdown menu. Should other genetic code be used, a user can modify one of the selectable genetic codes by first selecting particular genetic code from the menu and then changing the selection to "User Provided". The genetic code table can be completely replaced, but the format must stay exactly the same. One can find and copy-paste genetic codes from the Genetic Codes NCBI webpage.

SETTINGS

Plain text is just text without any formatting (i.e. from e.g. Notepad, but not MS Word). A fasta file is plain text sequence with a header in the form ">sequence name". A GenBank file contains a nucleotide sequence plus related information and feature definitions.
