A BLAST search is done to:
A)scan the database for a particular sequence.
B)find the chromosomal location of a sequence.
C)predict the three-dimensional structure of a protein from its amino acid sequence.
D)find restriction sites and SNPs in a sequence.
E)determine the conditions under which a gene is expressed.

A BLAST search is primarily used to scan a database for a particular sequence, either nucleotide or protein. It compares the query sequence to sequences in the database and returns matches that are statistically significant. BLAST can also identify conserved regions and motifs within a sequence, which can be useful for functional analysis. BLAST does not predict three-dimensional structures, determine gene expression conditions, or find restriction sites and SNPs (although it can identify regions that are conserved across species, which may include functional sites or conserved SNPs).
