Annotate a sequence

Quickly create annotations for regulatory regions, UTRs and more with the sequence editor.

Open Sequence Editor
Select sequence
Annotate sequence


Step 1: Open the sequence editor

First, you must find the biomodule or construct to which we would like to add the annotation, then view in the sequence editor.


Select sequence on the item card of the biomodule or construct to view it in the sequence editor.

Now we can select the sequence we would like to annotate. Here, we are selecting the entirety of the sequence with the select all tool. Alternatively, you can insert the start and stop positions for your annotation.

Step 4: Complete your annotation



Now we can select the type of annotation and add details to characterise that part of the sequence.


There are a wide range of annotations you can choose from, each with their own features for characterisation. Here, we will annotate a promoter, with features for characterising strength, type, cell affinity, origin and host species.


Choose the type of annotation you would like to add, name it and add a description.
