生物体：任何可以复制或传递基因物质的生物实体。
Organism: Any biological entity capable of replication or of transferring genetic material.
我们知道，准确性是基因传递中的一个必要原则。
We know fidelity is an essential principle of genetic transmission.
因此基因经常不能传递下去，除非是准确的复制。
So a gene usually cannot be passed on, unless it's an exact copy.
基因标记会在短时间内将新特性传递给下一代。
These genetic imprints can short-circuit evolution and pass along new traits in a single generation.
目前研究人员还没有搞清楚这种基因信息是如何从父代传递到子代的。
Researchers do not yet understand how the genetic information is transferred from father to child.
神经传递素并非个人基因形式转化为行动的唯一途径。
Neurotransmitters are not the only way an individual’s genetic make-up is translated into action.
就像癌细胞，基因缺陷或疯狂跑动的神经传递素，它们太小了。
Like cancer cells, faulty genetic code or neurotransmitters run amuck, they are too small.
就像癌细胞，基因缺陷或疯狂跑动的神经传递素，它们太小了。
