Abstract

Hypotrichs are a large group of ciliate species that cut, splice, reorder and eliminate DNA sequences to an extraordinary extent during their sexual life cycle. Such DNA processing occurs when a ciliate converts a copy of its germ-line nucleus into a somatic nucleus after cell mating.

摘要

寡毛纲纤毛虫是一大类纤毛虫物种，它们在有性生活周期中对DNA序列进行切割、拼接、重新排序和大量消除。这种DNA处理发生在纤毛虫细胞交配后将其生殖细胞核的一个副本转化为体细胞核时。
