Abstract
Palindromic sequences in single-stranded DNA and RNA have the potential for intrastrand base pairing, resulting in formation of "hairpin" structures. We previously reported a genetic method for detecting such structures in vivo in the yeast Saccharomyces cerevisiae. Below, we describe evidence indicating that a 14-base-pair palindrome (7 bp per inverted repeat) is sufficient for formation of a hairpin in vivo.
摘要
单链DNA和RNA中的回文序列具有链内碱基配对的潜力，可导致“发夹”结构的形成。我们之前报道了一种在酿酒酵母体内检测此类结构的遗传学方法。下面，我们描述了相关证据，表明一个14个碱基对的回文序列（每个反向重复序列7个碱基对）足以在体内形成发夹结构。
