Figure 7.14 The same DNA extract was amplified in the presence of (a) 0 ng/ µ l humic acid;
(b) 8 ng/ µ l humic acid; and (c) 12 ng/ µ l humic acid. The humic acid causes inhibition; at a
concentration of 8 ng/ µ l the profile has a similar appearance to the degraded profile in Figure 7.10,
with reduced peak heights at the larger loci; at a concentration of 12 ng/ µ l the profile is almost
completely absent
