General description
碘是一种深灰色固体，会升华成紫色气体。对于固体，碘分子具有高蒸汽压（0.31 mmHg at 25 °C）化学上，碘是亲电的，可参与亲电取代反应，如碘化有机化合物。这种亲电行为是由于碘原子具有高电负性和较大的尺寸，这使得它成为相对弱的氧化剂。我们合成的高纯度碘含有少于100 ppm的痕量金属杂质。

Timely and accurate expression of the genetic information relies on the integration of environmental cues and the activation of regulatory networks involving transcriptional and post-transcriptional mechanisms. In fission yeast, meiosis-specific transcripts are selectively targeted for degradation during mitosis by the
