For more information about how the prefix and suffix were determined and the special case of coding regions, see Assembly:RBS-CDS_issues.

Part Sequence

The DNA sequence for parts in the Registry starts with the first base of the part itself and ends with its last base. For example, a protein coding sequence is like this "ATG----------TAATAA". (Note: if you want to use a protein part with BioScaffold parts [1] to do things like directly make protein fusions from your part, then you should make a version of your part that has only one stop codon "ATG----------TAA" instead of two.) The sequence in the Registry does not include any bases of the BioBrick Prefix or Suffix.

Plasmids (see below) and primers or tags that explicitly specify prefix or suffix bases are exceptions to this rule.

BioBrick Prefix

The standard BioBrick prefix depends on the part that follows it.

If the following part is a coding sequence or any other part that starts "ATG", the BioBrick prefix is:

gaattcgcggccgcttctag

Otherwise, the BioBrick prefix is:

gaattcgcggccgcttctagag


BioBrick Suffix

The standard BioBrick suffix is always:

tactagtagcggccgctgcag


BioBrick Scar

When BioBricks with these prefix and suffix sequencees are assembled, there is a "scar" between these parts.

If the second part starts "AT", the scar is:

tactag

Otherwise, the scar is:

tactagag
