So for the bond order we want to take 1/2 of the total number of bonding electrons, so that's going to be 4 minus anti-bonding is 4, so we end up getting a bond order that's equal to 0.

键序等于1/2乘以,总的成键电子数，也就是4，减去反键电子数，也就是4。,所以最后得到键序为0。

When it's double stranded this gene can't be translated, because you have to have the single strand in order for the transfer RNA to bind and for this process of translation to take place.

当基因处于双链结构状态时,是不能进行翻译的,因为必须把双链拆开得到单链,才能结合转运RNA并开始翻译过程
