And one bit of evidence that these genes are implicated is that some unfortunate people have point mutations in these genes.
证明这些基因起作用的一些证据,是这些基因会在某些不幸的人身上,发生点突变
By looking to see not just what genes you carry but what genes are being used at particular times in your life.
这样不仅能够知道自己带有什么基因,还能知道哪些基因,在人生哪个时期发挥作用
So, evolution works at a level of the genes and because of that it could give rise to animals that are themselves altruistic.
进化论起作用的是我们的基因,因此进化论能产生,有利他主义的动物。
Basically, you're introducing this gene into cells that when you give the right inactive drug that will cause the cell to make chemicals that kill it.
概括来说,当你把这个自杀基因导入,含有特定未激活药物的细胞时,二者作用就使细胞生成了,可以杀死自己的化合物
It does that through a complex set of sort of cellular interactions, and it turns out also gene rearrangements if you go further to study that.
而这此过程中,发生了一系列复杂的细胞间的相互作用,也会涉及到基因重排,如果你们深入学习的话就会学到
If I took this same restriction enzyme and tried to cut the chromosomal DNA of a sickle patient, it wouldn't cut at that point because the wrong sequence is there.
而如果我用同样的限制酶,去切割病人的染色体DNA,那该酶是不会起作用的,因为基因序列不对
