Abstract
Two new and important features of introns have emerged from analysis of the Euglena gracilis chloroplast genome. One is a new class of introns, designated group III, that may be the closest contemporaries to nuclear pre-mRNA introns. The second is introns that are interrupted by other introns termed twintrons.
摘要
通过对纤细裸藻叶绿体基因组的分析，发现了内含子的两个新的重要特征。一个是一类新的内含子，称为III组，它可能是与核前体mRNA内含子关系最密切的当代同类。第二个是被其他称为双内含子的内含子打断的内含子。
