The RNA guide molecule can sometimes be imprecise, leading to unintended cuts to a patient's DNA. Moreover, because the tool breaks both strands in a DNA helix, the subsequent repair can also introduce unwanted insertions or deletions.
RNA 引导分子有时可能够精确,导致意外切断患者的 DNA。 此外,由于该工具会破坏 DNA 螺旋中的双链,因此后续修复也可能导致必要的插或缺失。
The 30% to 99% range that the researchers posit for the amount of Martian water stored in the ground is admittedly imprecise—and will likely narrow definitively only when humans can collect fresh samples and study them up close.
诚然,研究人员假设的 30% 到 99% 的火星地下水储量范围是精确的——只有当人类能够收集新鲜样本并对其进行近距离研究时, 这一范围才可能最终缩小。
