DNA microarrays have made a huge impact on genomic studies because they
A) can be used to eliminate the function of any gene in the genome.
B) can be used to introduce entire genomes into bacterial cells.
C) allow the expression of many or even all of the genes in the genome to be compared at once.
D) allow physical maps of the genome to be assembled in a very short time.
E) dramatically enhance the efficiency of restriction enzymes.

Question

Quizplus · Accepted Answer

DNA microarrays allow for the comparison of the expression of many or all genes in the genome at once. This has revolutionized genomics by enabling researchers to identify patterns of gene expression, discover new gene functions, and diagnose diseases based on gene expression profiles. The other options are not accurate descriptions of what DNA microarrays are used for.
