This pioneering project used a "shotgun" approach, which first isolates a DNA strand and forces it to copy itself millions of times over in a chemical reaction.
这一前沿工程使用了一种“猎枪”方法。首先分离出一个DNA链，之后通过化学反应使它复制自身上百万次。

The other (complementary or antisense) strand always has a sequence that matches the firststrand, with each C complemented by a G, and each A by a T, and vice versa.
另一条链（互补链或反义链）的序列总是与第一条链相匹配，即C与G，A与T，反过来也一样。
