cross-intron genomic DNA 跨内含子基因组DNA
It differs from the original DNA sequence in that it lacks intron and promoter sequences.
这样获得的DNA与原始的dna序列的不同在于缺少内含子和启动序列。
DNA were extracted from the peripheral blood, then TG sequence in second intron of IL - 4 was amplified by PCR, the polymorphism of that segment were then detected through 8% polyacrylamide gel.
首先从实验对象的外周血中提取DNA, pcr扩增il - 4的第二个内含子中的一段TG重复序列,然后用8%的聚丙烯酰胺凝胶电泳检测这段基因的多态性。
To understand intron 15 of human LDL receptor gene, the DNA fragments from exon 15 to exon 16 and the 3' end of intron 15 were amplified with long chain PCR and anchored PCR.
为了解人类LDL受体基因内含子15的遗传背景,利用长链PCR和锚定PCR分离了LDL受体基因外显子15-内含子15-外显子16和内含于15的3’末端片段。
One is the processing has already been done so the introns are already out, so you don't have to figure out what's exon and what's the intron, it's already done for you.
一是DNA已经过处理,内含子已经没有了,你不用分辨哪些是外显子哪些是内含子,这些都已经帮你做好了
