Final answer:
The type of search performed at the TAIR database is a sequence tag method search using the MASCOT search engine. Various parameters are set for the search to identify proteins.
Step-by-step explanation:
The type of search that would be performed at the TAIR (The Arabidopsis Information Resource) database is a sequence tag method search. This involves using the MASCOT search engine to analyze data files obtained from the database.
The search parameters include the use of the NCBInr database, green plants taxonomy, trypsin digest enzyme, and various modifications and tolerances for peptide identification.
