chromatics = chrom(颜色) + at(地点) + ics(学科) = 色彩学
chromate = chrom(颜色) + ate(盐类) = 有颜色有光泽的盐类→铬酸盐
染色体
chromosome
常考释义
Every time the Chromosome divides, every time one cell divides into two, pieces of the ends of the Chromosome, the telomeres, get broken off.
每次染色体分裂,一个分裂成两个,染色体的尾部,也就是端区,就会发生断裂。

Do we have a chromosome like that?
那么我们真的有那么一条染色体么?
And it contains the diploid number of chromosomes, genes.
它含有二倍体的染色体基因。

And in the future, we may have virtually immortal nerve cells and immortal skin cells of whatever because these chemical, telomerase can keep the telomere on the ends of Chromosomes from getting any shorter.
在将来,我们可能有真正意义上的长生不老的神经细胞、皮肤细胞等等,因为端粒酶可以构建端粒,使得染色体不会变得更短。

当端粒从染色体中断裂开,这种化学物质,这个端粒酶可以重建它,可以重新组装这个具有保护功能的DNA,也就是染色体失去的端粒。

所以这看上去⋯⋯通过观察一些特定的染色体的端区,我们可以预测多长的染色体可以成功分裂。

也就是23对染色体,在人体细胞中,每个有特定的长度和大小。
