The regions that are necessary for describing what the protein is like are called exons, the regions that are not are called introns.

因此我们把编码蛋白质的区域,称为外显子,而把不参与编码蛋白的区域称为内含子

There are encoding regions called exons and those are interrupted by non-coding regions called introns.

编码蛋白质的部分叫外显子,外显子被不编码蛋白质的内含子打断

If I cut up just DNA from the chromosome, what's called genomic DNA, then I'm going to have both exons and introns within the fragments that I create.

如果我切割的恰好是染色体上的,基因组DNA,那我切成的片段上,就会同时有外显子和内含子

耶鲁公开课 - 生物医学工程探索课程节选

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
