For children, inhalers should be used with spacers.

对于儿童，吸入器应该与储雾罐一起使用。

And in between these repeats are unique sequences called spacers.

这些重复之间的独特被称为" 间" 。

The spacer helps get the medication deep into the lungs instead of just in the mouth.

储雾罐可以帮助药物深入肺部，而不口腔内。

Now it turns out that the spacers in CRISPR locations are kind of a historical record of DNA viruses that have previously infected the host.

现证明CRISPR位点上的间是早先感染过宿主的DNA病毒下的一种历史记录。

So when a DNA virus gets into a host cell, certain fragments of it called Protospacers are incorporated into the host's genome, becoming the spacers in CRISPR locations.

当DNA病毒进入宿主细胞时，其被称作" 原间" 的特定片段会被整合进入宿主基因组变成CRISPR位点上的间。

The inhaler, spacer, and mask can be bulky to carry around, but all people with asthma need to have their rescue medicines close by at all times.

吸入器、储雾罐和面罩携带起来可能比较笨重，但是所有哮喘患者需要随时都携带他们的救援药物。

What's left are mature crRNAs each made of the complements to both the 3 prime repeat and about 20 nucleotides of a spacer, still bound to tracrRNA.

下的成熟crRNA依然与tracrRNA结合，每一个都由重复互补链的3'端和间互补链约20个核苷酸组成。
