Figure 10.2 This scientist is examining a microarray slide. The pattern
of binding of the test samples, to the array of DNA on the slide, is
displayed on the computer screen. Libraries of small chemicals can also
be analyzed for their ability to bind to DNA or protein microarrays in a
search for potential new drugs.
patients decide if further drug treatment is necessary. DNA micr-
oarray technology is also used to tell drug researchers what form of
several genes a subject has inherited—information important in
how the body breaks down drugs. This may predict whether the drug
will build up in the body, leading to toxic effects. Drug companies
are working to see if these methods will allow drugs to be tested and
even used more safely (Figure 10.3).
