This condition leads to shortened red blood cell survival, and subsequent anaemia, often called sickle-cell anaemia.

这一状况导致红血球存活期缩短，继而发生贫血，通常称之为镰状细胞贫血。

In a normal cell DNA that DNA in the normal cell - this DNA gets cut by the restriction enzyme, so the sickle gene ends up - so that hemoglobin gene ends up in two pieces.

一个正常细胞的DNA,正常细胞里的DNA,会被限制酶所剪切,因此镰状血红蛋白基因--,不对,是正常血红蛋白基因被切成两段
