To explore the evolution and function of introns in eukaryotes, we have developed an intron sequence information system (ISIS; http://isis.bit.uq.edu.au/) which ...

The molecular basis for the consensus sequence at the 3' ends of introns ... Within this complex, intron excision occurs in two steps, each a single transesterification reaction.

The segments in question are introns, short sequences of a subset of transfer ... In experiments exposing cells to oxidative ...

They are DNA sequences that interrupt the sensible protein ... we have so far that spliceosomes could be able to reinsert an intron back into the genome in another location. This is an ability ...
