How can I designate a feature within a DNA sequence?
Select the sequence region that will be labeled with a feature. In this example, a multiple cloning site (MCS) has been selected in Sequence view.
To add a feature, click Features → Add Feature... .
(1) Type the name of the new feature.
(2) Specify the feature type (according to GenBank conventions) and directionality (nondirectional, forward, reverse, or bidirectional).
Click the "Color" button. Choose a standard color, or click More Colors... . To display the feature as a thin black line, click No Color.
If desired, enter a description in the "/note" field. Once the feature has been created, the contents of this field will appear in a tooltip if you mouse over the feature.
Click OK to see the new feature.
