• The user queries the client– Ask the user to chose one query from the list.– The user should send the request to the client.– Ask the client to write down the query

• ID:start,stop

DAS Game

Play the game 2/3• The client retrieves sequence information

– Find protein reference source• The client should ask the registry if there is any

source providing protein sequences.• The client should get in return the name and

location of the protein reference source.– Request sequence

• The client should ask the protein reference source if there is any sequence for ID and if so the client should request just the specific range.

– Protein reference server dictates the sequence– The client writes on the board the sequence

DAS Game

• The client retrieves features (annotations)– Find protein annotation sources

• The client should ask the registry if there is any sources providing protein features.

• The client should get in return a list of names and locations of protein annotation sources.

– Ask the client to write down these list.

– Request annotations• The client should ask each protein source from the list

if there is any features for the selected ID. If so the client should request just features from the specific range.
