point mutation

基本解釋

Conclusion:The point mutation in this area of mitochondrial DNA might not be related hereditary ataxia.
結(jié)論：遺傳性共濟失調(diào)的發(fā)生、發(fā)展可能與該區(qū)域點突變無關(guān)。
Twenty cases(20/31) were selected randomly for DNA sequencing. No point mutation of ABCB4 gene exon 23 were detected.
隨機挑選20例標(biāo)本測定外顯子23的DNA序列，未發(fā)現(xiàn)點突變。
This single- point mutation engages the leg- making apparatus of the embryo fly to build a leg where its antenna should be .
這個單點突變攪亂了果蠅胚胎的足肢生成裝置，在原本應(yīng)該是觸角的地方生出一條腿來。

But you see the difference. Great question, and a very important thing to understand, and that's why I'm belaboring this point, since this is where people tend to get pretty confused, and this is why mutation is very important to understand. Yeah.
但是你們已經(jīng)發(fā)現(xiàn)區(qū)別了，這問題挺好的，并且有重要的一點需要我們?nèi)プ⒁獾氖牵藗兘?jīng)常對可變性這一點感到很迷惑，但是可變性是很重要的,我們需要理解它,這也是我經(jīng)常強調(diào)這一點的原因。
