1·But there was still a very different physiological challenge for these organisms than for the more evolutionarily ancient single-celled organisms such as bacteria.
然而与进化上更古老的单细胞生物如细菌相比这些多细胞生命面临着一个非常不同的生理挑战。
2·In this paper, we present a novel approach to identifying evolutionarily conserved protein-coding sequences in genomes.
在本文中,我们提出了一个新的方法,在基因组中确定进化上保守的蛋白质编码序列。
3·CXCR4 presumably serves as a guidance molecule that is highly conserved evolutionarily among mammalian NSCs, including in humans.
CXCR4可能是哺乳动物(包括人)神经干细胞中的一种进化上高度保守的引导分子。
4·The aging process is evolutionarily conserved and subject to quantitative modification by both genetic and environmental factors.
衰老过程是进化上保守的和定量的修改须经双方遗传和环境因素。
