Figure 5.

A-to-I editing tree of a normal control sequence. The editing tree was created from the alignment of the cDNA sequences with the DNA sequence. The root of the tree is the DNA sequence and the gray nodes are the edited RNA sequences. The empty nodes are intermediate stages between the DNA and RNA, that were not detected in the library, but were deduced by the program. The numbers in the grey nodes are the numbers of copies found in the alignment where the root of the tree also includes the number of exact copies of the DNA sequence. The numbers beside the edges represent the location of the editing event separating each node from its parents. Every editing event represented by a node is found in all its direct and indirect descendents.
