Figure 5-8. Sizes and positions of partial UGT sequences (cross-hatched rectangles) from
 intestine and liver, corresponding to two distinct isoforms, relative to
 complete sequences for liver and intestinal UGT (solid rectangles).

 The -AAAA indicates 3'-polyA tail while the suffix _PCR indicates amplicons
 that were not cloned but sequenced directly.
