And they found that the plants that bounce back after clipping boost their DNA content-some of their cells go from having 10 chromosomes to having 320.
他们发现,那些受损后迅速恢复的植物dna含量暴增——其中一些原本只有10个染色体细胞,已经拥有了320个染色体。
They include constraints imposed "from below" by physics and chemistry, that is, from molecular interactions upwards, through genes, chromosomes, cells, tissues and organisms.
包括来自于“底层”的物理和化学因素,也就是分子间的作用,影响了上层的基因、染色体、细胞、组织和生物体。
And the size of the nucleus needed to contain all those chromosomes may make those cells bigger and bigger cells means a bigger plant.
细胞核增大以容纳暴增的染色体,相应地细胞也会增大,更大的细胞意味着更大的植株。
