These primers bind to DNA sequences that are similar across species, then amplify genetic barcodes that are species-specific.

这些引物会结合不同物种间相似的 DNA 序列，然后扩增出具有物种特异性的基因条形码。

So epigenetic silencing of a gene means turning it off while keeping the DNA sequence itself the same.

基因的表观沉默是指，在DNA核苷酸序列不变的情况下，抑制基因的表达。

The more similar the DNA sequences are, the more closely, it can be presumed, the two individuals are related.

两个个体的DNA序列越相似，他们在亲缘关系上则越接近。

It's basically part of the bacteria's immune system — it remembers DNA sequences from attacking viruses and chops them up in specific places.

In the word " epigenetic" , " epi" means outside of, and " genetic" refers to the DNA sequence of A's, C's, G's, and T's.

（表观遗传）这个词中，“epi”表示在...外面，“genetic”表示A、T、C、G组成的DNA序列。

And in total, they analyzed over 1200 DNA sequences from 26 populations worldwide.

他们总共分析了来自全球 26 个人群的 1200 多个 DNA 序列。

Rather than patenting every conceivable variant, the company claims jurisdiction over isolated DNA sequences, 15 base pairs long, that match short parts of the genes.
