A highly conserved genetic program "intrinsic" to germ cells determines the sequence of events that underlies germ cell development.
一个对于生殖细胞高度保守的“内部的”遗传程序决定了构成生殖细胞发育基础的事件的发生顺序。

By comparing a portion of DNA structure across 36 different species, the team estimates that 12% of the human genome is conserved - twice the estimate based on sequence conservation.
Although having great variance in sequence, group I introns share a number of conserved base-paired regions, which take part in the formation of the catalytic structure.
