18M.3.HL.TZ2.12a.i

A protein expressed by the gene carotene desaturase (CTP1) was introduced into Golden rice (Oryza sativa) through genetic engineering. Bioinformatics were used to determine if the protein sequence matched any allergenic proteins (proteins that trigger an allergic reaction). The table shows the results from the alignment of the CTP1 protein with proteins from moth, soybean and dust mite that are known to be allergenic.

(a.i)

State a bioinformatic search tool that could be used to perform the alignment.
