thank you!

Here's my attempt at translating using 3 online dictionaries plus what I already know.

λ 噬菌体基因组有7个HindiIII 酶切位点 = Lambda [11th Greek letter] bacteriophage genetic groups have 7 HindiIII enzymes corresponding to sites?

用HindiIII 酶切其基因组DNA 后, 形成 8 个片段 (23130bp, 9416bp, 6557bp, 4361bp, 2322bp, 2027bp, 5646bp, 125bp)

= After using HindiIII enzymes to correspond to its genetic groups, DNA forms into 8 extracts (23130bp, 9416bp, 6557bp, 4361bp, 2322bp, 2027bp, 5646bp, 125bp).

经琼脂糖凝胶电泳后, 理论上这 8 个 DNA 片段所形成的条带的亮度

= After regular agarose gel electrophoresis, in theory, these 8 DNA extracts which forms the strip's illumination.

应按其质量的大小依次减弱

= Should go according to the quality size depending on the reduction in weakness.

然而在某些情况下, 实际电泳图象中 4361bp 的 DNA 条带亮度明显低于低于其小

的 DNA 片段条带亮度 (2322bp, 2027bp)

= However, under certain situations, in practical visual phoresis, 4361bp's DNA strip illumination obviously lower than when compared to the smaller DNA extract strip illumination (2322bp, 2027bp).

请问这是什么原因? = What is the reason for this if I may ask?

I think 酶切位点 normally refers to the recognition sites (or cutting sites) of certain restriction enzymes, in this case the HindiIII 酶. But I could be wrong.
