470. 猛犸象RNA测序：古代基因活性之窗
from 知为谁 · host 知为谁
这篇文章主要介绍了科学家对一头名叫Yuka的猛犸象进行研究，从中测序出了近四万年前的古老RNA，创下了新的世界纪录。RNA的保存和测序被认为比DNA更困难，因此这一发现被认为是科学上的巨大突破。测序出的RNA能够提供基因表达的直接证据，让研究人员得以窥见猛犸象生命最后时刻的生物学活动。研究人员相信，这项工作不仅有助于理解已灭绝动物的生活方式，还可能为测序古代RNA病毒铺平道路。研究成果表明，在理想的保存条件下，RNA的存活时间比先前认为的要长得多。内容来源：https://www.sciencealert.com/yuka-the-woolly-mammoth-just-gave-us-the-oldest-rna-ever-sequenced
