intense program of passage in cell culture or animals with ACE-2

Furthermore, the generation of SARS-CoV-2 by cell culture or animal passage would have required prior isolation of a progenitor virus with a very high genetic similarity. Subsequent generation of a polybasic cleavage site would have then required an intense program of passage in cell culture or animals with ACE-2 receptor similar to humans (e.g. ferrets).

• 你引用的原文并没肯定是人工合成的，并列提了动物形成。咋你的主贴就变成了结论是人工合成呢？ -古安- ♀ (0 bytes) () 03/13/2020 postreply 21:09:31

• 读原文, 读懂原文. 你自信比石正丽更知道她发现的病毒和她进行的跨种群传播 -janeice65- ♀ (0 bytes) () 03/13/2020 postreply 21:22:06

• 在活体动物或者人中进行强行传代怎么到你嘴里就成了自然选择的一部分了 -janeice65- ♀ (0 bytes) () 03/13/2020 postreply 21:25:40
