| Abstract: | A new class of introns that possess AT and AC respectively at their 5' and 3' ends, has been identified in eukaryotic genome. The AT AC introns differ from the major class of pre mRNA introns both in structural features and in splicing mechanism. The distribution, structural features and splicing mechanism of AT AC introns are discussed and compared with major class of introns. |
