These RNAs slow growth and prevent females from becoming fertile, essentially dooming them to be workers.

这些 RNA 会减缓生长并阻止雌性变得可育，从根本上注定它们将成为工人。

But the weird thing is: these tiny RNAs from plants can survive digestion and pass into animal cells through the food they eat.

但奇怪的是：这些来自植物的微小 RNA 可以在消化后存活下来，并通过动物所吃的食物进入动物细胞。
