A simpler form of DNA may be key to non-viral gene therapy, study suggests
研究称：更简单形式的DNA或是非病毒基因疗法的关键

There’s no more iconic shape in biology than the twisting strands of DNA. Yet that same double helix that makes the molecule instantly recognizable may also be the very thing holding back cheaper, safer, and more effective forms of gene therapy, according to new research.
在生物学中，没有哪种形状比扭曲的DNA链更具标志性。然而，新的研究表明，使这种分子一眼可辨的双螺旋结构，或许正是阻碍更便宜、更安全、更高效的基因疗法形式的关键因素。
