Voice 2: It is your Deoxyribonucleic acid, or DNA. Some people call DNA the building blocks of life. Everyone has his or her own set of DNA. It influences every part of a person's body.
聲音2：這就是脫氧核糖核酸，簡稱DNA。有人認為DNA是構筑生命的基石。所有人都有自己的一套DNA。它影響人們身體的各個部分。
Voice 1: And it has millions of different parts to it. But there is something truly surprising about DNA. When scientists really began to look at people's DNA they discovered that people are not really that different from each other. On the outside of their bodies people look different from one another. But when you get down to it, everyone is made of the same stuff!
聲音1：DNA由數百萬個不同的部分組成。但是DNA有令人極為震驚的內容。當科學家開始研究人類DNA時，他們發現人們彼此之間并沒有那么不同。從外觀來說，人們彼此長相不同。但是當你認真研究時，會發現所有人都是由相同特征構成的！
Voice 2: DNA is a very complex subject. Before nineteen fifty-three scientists did not even know what DNA really looked like! They knew that something told a person's body how to grow. But they did not know how. Scientists have been trying to understand DNA ever since they discovered it.
聲音2：DNA是一個非常復雜的主題。在1953年以前，科學家甚至都不知道DNA長什么樣子！他們知道有某種物質決定人體如何生長。但是他們不知道是如何決定的。自從發現DNA以來，科學家一直在試圖理解DNA。
