Figure 2
Frequencies of polyadenylation signal-like sequences upstream of 3′ end. Frequencies of polyadenylation signal-like sequences located upstream of 3′ end sites were plotted. The sequence pattern AATAAA/ATTAAA was searched for every position from the 3′ end of the 4280 largest-candidate set. The set contains 1395 sequences, which contain polyA-signal like sequence in the 3′ end, as mentioned in Table 3.
