Final answer:
The claim that Hwang Woo Suk successfully cloned a human embryo is false. Cloning is a complex and often unsuccessful process, and human cloning is banned in the United States. Therefore given statement is false
Step-by-step explanation:
The statement Hwang Woo Suk successfully cloned a human embryo is false. While there have been attempts at producing cloned human embryos, primarily for embryonic stem cells and therapeutic purposes, the ethics and practical challenges have hindered the progress and practical application in human cloning. Moreover, cloning is not a simple process; it requires many attempts before achieving success, as evidenced by the 277 tries needed to clone Dolly the sheep. Additionally, animal clones often exhibit abnormalities and there are substantial ethical concerns surrounding human cloning. In the United States, human cloning is banned, largely due to the potential for miscarriages, stillbirths, deformities, and the unresolved ethical issues.
