專業人士幫忙翻譯分子生物英文段落翻成中文~勿用翻譯網

Often,it is important to determine the sizes of DNA bands on gels after electrophoresis. This may easily be done if marker DNA samples on the gel. The marker DNA sample contains a number of DNA molecules,each with a known molecular size. For example,bacteriophage lambda genomic DNA digested with HindIII has 8 fragment of 23130,941,6557,6361,2322,2027,564,and125 base pairs(The 125 bp fragment is often not seen in experiment,either because it is too faint or because it runs off the gel. This band will be ignored in the rest of the tutorial.) an example of a gel with this DNA marker and some “unknown” DNA sample is shown in the illustration.

    通常,決定電泳後瓊膠中DNA片段的大小是很重要的。如果標定瓊膠中DNA樣本這可能會輕易地做到。 標定DNA樣本包含大量的DNA分子,每株都有已知的分子大小。 例如,以HindIII酶切的lambda噬菌體染色體雜交品種有8片段23130, 941,6557,6361,2322,2027,564及125鹼基對(第125基對片段不是因為太模糊就是因為從瓊膠中釋出,經常不會在實驗中出現。此片段在本輔導課程的其餘部分將被忽略)。 圖解中顯示一個標定DNA與一些“不明”DNA的瓊膠樣本實例。
