exon是什么意思 exon的中文翻译、读音、例句

1. 词义:Exon是指基因的部件,它组成蛋白质合成的指令。它是脱离掉基因组中的内含子后的一个片段,不受RNA剪接的影响。

2. 词性:Exon是一个名词。

3. 词组搭配:

- Exon skipping (外显子跳跃):是一种基因剪切疗法,适用于一些遗传病的治疗。

- Exon shuffling (外显子重组):是指在基因组中,由于某些突变、复制或转位事件等,外显子的位置发生改变。

- Exon junction complex (外显子连接复合物):是指由外显子边界处的蛋白复合物形成的结构,它与RNA后处理和核糖体的招募有关。

4. 短语:N/A

5. 发音拼写:[ˈeksɑn]

6. 例句:

- The mutation in the exon region caused a severe genetic disease. (突变出现在外显子区域,导致一种严重的遗传病。)

- The exon skipping therapy was effective in treating Duchenne muscular dystrophy. (外显子跳跃疗法在治疗杜兴肌肉萎缩症方面有效。)

- The exon junction complex plays a crucial role in recruiting the ribosome. (外显子连接复合物在招募核糖体方面发挥了关键作用。)

- The exon shuffling event led to the formation of a new protein with novel function. (外显子重组事件导致了新蛋白质的形成,具有新的功能。)

- The sequencing result revealed a mutation in the third exon of the gene. (测序结果显示该基因第三个外显子处出现了突变。)

'exon' 不是任何国家的语言,它是英语单词 'exonuclease' 的缩写形式,意为“外切酶”,是一种能够切除DNA或RNA分子末端的酶类蛋白。

常见翻译:

外切酶

用法:

exon 在分子生物学中常用于描述基因结构,指编码蛋白质的区域,与 'intron'(内含子)相对应。

例句:

1. This gene has four exons and three introns.(这个基因有四个外显子和三个内含子。)

2. The exonuclease activity of the enzyme was measured.(测定了酶的外切酶活性。)

3. The DNA polymerase can proofread exonuclease errors.(DNA聚合酶可以校正外切酶的错误。)

4. Mutations in the exon region can result in genetic diseases.(外显子区域的突变可能导致遗传疾病。)

5. The transcription process involves the splicing of exons.(转录过程涉及外显子的剪接。)

6. The introns are removed to create the mature mRNA with only exons remaining.(去掉内含子后留下外显子,形成成熟的mRNA。)

7. The primers were designed to amplify a specific exon of the gene.(引物被设计用来扩增基因的一个特定外显子。)

8. Alternative splicing can generate different mRNA isoforms from the same set of exons.(选择性剪接可以从同一组外显子生成不同的mRNA亚型。)

9. The exonuclease is used in the purification of DNA fragments.(外切酶用于DNA片段的纯化。)

exon的中文翻译是外显子,读音为[ˈeksɒn]。

例句:

1. 这种基因拥有三个外显子。

This gene has three exons.

2. 该研究发现某些变异体仅影响外显子,而不影响内含子。

The study found that certain variants only affect exons, not introns.

3. 在基因表达中,外显子与内含子有不同的作用。

In gene expression, exons and introns have different functions.

exon在英语中代表"外显子、埃克森"的意思,在日常中也代表"人名"的意思,单词读音音标为[exon],在英语中以名词出现较多,在《英语发音在线词典》中,共找到50个与exon相关的例句。

Exon的释义

1.外显子

例句:Several strains of meat-type and egg laying chickens were found to segregate for an HindIII RFLP located in the intron preceding exon 4. (几株肉型和产蛋的鸡被发现隔离的酶切多态性位于第4外显子内含子前面。)

2.埃克森

例句:Methed Unsymmetrical PCR was used to amplify HLA A gene exon 2,3. The PCR products were used as templates for hybridization. (方法采用不对称PCR方法,扩增HLA A基因的第2 ,3外显子,荧光标记扩增产物,作为杂交模板。)

3.人名

例句:Results the DHPLC find the exon 7, 9 polymorphism. (结果:变性高效液相色谱检测出7、9号外显子多态性。)

4.生化、人名

例句:The effect of skipping just one exon can be dramatic for an organism. (翻译:仅仅略过一段表现子,就可能对生物体造成显著的影响。)

用法及短语

exon一般作为名词使用,如在exon exchange(外显子互换)、exon shuffling(外显子混编)、exon skipping(外显子跳读)等常见短语中出现较多。

exon exchange外显子互换

exon skipping外显子跳读
exon trapping外显子捕获
Exon.n. 〔遗〕外显子;编码顺序;基因外区;外子\n[网络] 编码顺序(exonextron);表现序列;显译子
exon trapping method[医]外显子截留法[用于确定基因组序列中的外显子]

例句

1. Results the DHPLC find the exon 7, 9 polymorphism. (翻译:结果:变性高效液相色谱检测出7、9号外显子多态性。)

2. The effect of skipping just one exon can be dramatic for an organism. (翻译:仅仅略过一段表现子,就可能对生物体造成显著的影响。)
