1·There is same bases usage frequency in coding sequence between leading strand and lagging strand.

先导链与滞后链编码序列的碱基使用频率基本一致。

2·Basically, a DNA strand is pushed through a 2nm hole on a silicon chip and, as it moves through, that chip is able to use an electrical charge to read the strand's coding sequence.

DNA链被拉进硅基芯片上的直径2nm的孔，随着它穿过小孔，该芯片可以通过电荷读取到链上的编码序列。

3·The result show:1 there is same bases usage frequency in coding sequence between leading strand and lagging strand 2 There also same bases usage frequency in first codon, second codon and third codon.

先导链与滞后链在第一、第二、第三密码子碱基使用频率基本一致且显著正相关。
