(<FONT COLOR="#BABABA">part in grey</FONT>, <FONT COLOR="#CC00FF">PstI</FONT>, NotI,<FONT COLOR="#FF5333"> SpeI</FONT>). YOUR SEQUENCE as it should be entered into the database is in uppercase letters.

Basic Information
|
|
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". 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
|
