超声步骤为冰上3次 5秒的超声(50% 输出功率),控制超声探头位置,避免产生气泡。如没有超声仪,可用1mL注射器针头,冰上反复抽打裂解液5-10次,达到类似于超声的效果。

Sexual antagonistic co-evolution is the relationship between males and females where sexual morphology changes over time to counteract the opposite's sex traits to achieve the maximum reproductive success
In evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process in which absence of recombination, especially in an asexual population, results in accumulation of deleterious mutations (harmful mutations) in an irreversible manner.
Sexual dimorphism is the condition where the two sexes of the same species exhibit different characteristics beyond the differences in their sexual organs. The condition occurs in many animals and some plants.
对我6+年的phd只有两个诉求
1. 英语太烂了,想要英语尽量close to native,能够自由地表达自己的情感,以及和别人自在地讨论research
2. 尽量knowledgable in biology especially in my field,能够自信地给别人解答问题,对biology有自己地见解和追求
别的真的无所谓
