How can I add an intron annotation to a translated feature?
In this example, a Saccharomyces cerevisiae tubulin gene has been annotated as a translated feature. The intron has not yet been specified, and as a result, the translation contains stop codons.
According to the Saccharomyces Genome Database, the intron lies between bases 26 - 141. To specify such a numerical range click Edit → Select Range... , type the range, then click Select.
To remove the intron from the feature, click Features → Delete Feature Segment....
When the Edit Feature dialog appears, click OK.
A dashed line will now mark the intron. The translation will adjust to span the intron boundaries. In this example, the codon for Valine-9 is split between the two exons.
