In animal clning, animals are prduced in a lab by using DNa that is taken frm the cells f a naturally-brn animal. T clne Zhngzhng and Huahua, scientists frm the Chinese Academy f Sciences first remved the nucleus（细胞核）frm a mnkey’s egg cell. They then put anther nucleus taken frm the mnkey’s bdy cells int the egg cell. The newly-frmed egg was put int the wmb（子宫）f a female mnkey. Finally, Zhngzhng and Huahua were brn.
The clning prcess is hard, especially remving the nucleus. It needs t be dne in a fast and precise（精确的）way. The faster yu d it, the less damage is dne t the egg, accrding t CAS. Scientist Liu Zhen spent three years practising remving the nucleus.
Unlike cmmn mnkeys, them unlike cmmn mnkeys, clned mnkeys have the same DNA as each ther. When ding experiments n them, scientists can easily knw that certain results are caused by different treatments, rather than different genes.
Accrding t Sun Qiang frm CAS, mst drug trials（药物试验）are dne n lab mice. Hwever, drugs that wrk n mice might nt wrk n humans. The tw species are very different.
“Mnkeys and humans are clsely related and testing n mnkeys is suppsed t be as effective as testing n humans,” Sun added.
