How we did it

 

Steps

1. Start with the ENA browser Text Search on the homepage.

2. Type the search term AB212907 into the text search box.

3. Scroll down to the graphical Overview section.

Graphical overview section of EMBL-Bank entry AA212907, where the blue box/arrow tells you the app promoter is from Anopheles stephensi, the red box/arrow tells you the DsRed CDS (coding sequence) is a synthetic construct, and the green box/arrow tells you the Antryp1 terminator is from Anopheles gambiae.

Steps

1. Scroll down to the Source Feature(s) section. This section describes the source of the sequence in more detail, including the nucleotide ranges for each region of the sequence.

Steps

1. Scroll down to the Other Features section. This section provides more detail on the associated features of each sequence region, which were summarised in the graphical Overview section.

2. If the accession number AB212907 was not known, you could have done a text search on the terms: Anopheles stephensi AND TGN, which restricts the taxonomic search to the transgenic class (TGN) of EMBL-Bank.
