Abstract:
:Here we advocate the use of 2-dimensional data representation in the context of the informational approach of sequence analysis (Claverie & Bougueleret (1986) Nucleic Acids Research 14, 179-196) by applying these methods to the problem of intron/exon discrimination. Two main findings are reported: i) oligonucleotide patterns complementary to the Ul small nuclear RNA are specifically avoided in exon sequences, ii) vertebrate intron sequences, to the exclusion of other eukaryotic phyla, are characterized by a peculiar distribution of CpG containing patterns.

The minimal 'cap0' consists of N7-methylguanosine linked to the first nucleotide via a 5'-5' triphosphate (ppp) bridge. Cap0 is further modified by 2'-O-methylation of the next two riboses, yielding 'cap1' (m7GpppNmN) ...
