But over the past 10 years, new tools developed for exploring the human genome gave ancient DNA research a lifesaving infusion.
但过去十年间，探索人类基因组研发的新工具拯救了古生代dna的研究。
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。
To put this in perspective, some scientists have guessed that all the particles in the universe are probably less than 10 with 76 zeros behind it, far less than the possibilities of your DNA.
从另一个角度看，有些科学家猜测，宇宙间所有的微粒子大约少于10后面加76个零，远少于DNA的可能性。
