Question

A BLAST search can be used for which of these applications?
A)to compare a nucleotide or amino acid sequence to databases from a variety of species
B)to display the reading frame of a nucleotide sequence
C)to determine whether a gene has an essential function in an organism
D)to analyze microarray data
E)to visualize the locations of all the genes on a single chromosome

Accepted Answer

BLAST (Basic Local Alignment Search Tool) is primarily used to compare a nucleotide or amino acid sequence against databases containing sequences from various species to find regions of similarity, which can help in identifying the function, family, or evolutionary relationships of the sequence in question.
