Search for occurrences of a DNA motif

Please choose a genomic DNA sequence from the box.


When entering your nucleotide sequence, you may use IUPAC notation.

A variable-length consensus sequence may also be entered in a format to reflect the unknown number of nucleotides

e.g. AAGS(3,8)TTN(3,20)TTGAC
In this example a C or G can appear 3 to 8 times starting at position 4 (indicated in blue) and any nucleotide can appear 3 to 20 times starting at the position following the the second T (indicated in red).
