我们从中得到的信息使研究人员相信，毒液蛋白在医学研究领域的应用或有令人惊喜的效果。

What separates colubrids from other snakes we have been classifying as venomous, is not the lack of venom, but the lack of an effective way to deliver the venom into its prey.

将黄颌蛇与其他被我们归类为毒蛇的蛇区别开来的，并不是它们没有毒液，而是缺乏一种将毒液输送到猎物体内的有效方法。

In most venomous snakes, like vipers and cobras, the venom is used to catch and inmoblize the prey; but in colubrids, venom drips onto the prey only after the prey is in the snake's mouth.

在大多数毒蛇中，如蝰蛇和眼镜蛇，毒液用于捕捉猎物、使其无法行动；但在彩颌类中，只有在猎物到了蛇嘴里后，毒液才会滴到猎物身上。

By analyzing the DNA, the genetic material of the proteins, the researchers could focus on the toxic genes and use them to trace the evolution of snake venom, and from this, the evolution of snakes.

通过对 DNA 及蛋白质中的基因物质进行分析，研究人员可以专注于有毒基因，并利用它们得到蛇毒的进化轨迹，这样也就知道了蛇的进化源。
