to make or do something again in exactly the same way

Researchers tried many times to replicate the original experiment. 研究者们作了很多次努力，试图重复这一实验。

If organisms and genetic or other structures replicate, they make exact copies of themselves.

Chromosomes replicate before cells divide and multiply. 染色体自我复制后，细胞便开始分裂、繁殖。

Computer viruses replicate themselves and are passed along from user to user. 计算机病毒自我复制并从一个用户的计算机传到另一个用户的计算机上。
