Repeats – Dyad

This method locates all dyad repeats that exceed a specified length and are located within a defined proximity. This proximity is defined in the method parameters. A dyad repeat exists when one region of DNA is followed shortly thereafter by its mirror image. An example is:

TAGCGA…AGCGAT

To change method parameters:

1. Double click on the method name in the Method Curtain; or select the method display and then Analysis > Method Parameters.

2. Type the Minimum Length for your repeats in the appropriate window.

3. Click No Limits if you don’t want to limit the distance between dyad repeats or click Less Than to open a text box where you can specify a maximum repeat distance.

Note that this method searches only one strand. The complement of any dyad repeats found occurs on the opposite strand.
