1·Scientists have now discovered that these viruses have integrated themselves into the DNA of a wide range of animals, including humans, zebrafish, and other vertebrates.
科学家如今发现这些病毒已将自身整合成大多动物的DNA，其中这些动物包括人类、斑马鱼以及另外的脊椎动物。
2·Like a blues musician tapping his foot to the music, zebrafish can learn to flap their tails to the rhythm of a flashing light — and remember the beat after the light has gone out.
就像蓝调音乐家脚踏音乐节拍一样，斑马鱼也能够学会跟着闪光的节奏左右摆动尾巴——并且在光熄灭之后还记得这些节拍。
3·By rewinding the video of a zebrafish embryo, the researchers were able to trace the origin of cells that formed specific tissues, such as the retina at the back of the eye.
通过回放斑马鱼胚胎的录像，研究者可追寻出组成特定组织比如它眼球上的视网膜的原细胞。
4·In the latest study, the scientists used a genetic trick to make zebrafish turn green when the p53 gene was switched on to explore the way it was regulated.
在最近的研究中，科学家利用一种基因技巧使在p 53基因打开的时候，让斑马鱼变成绿色，来探索这种基因的调节方式。
5·Normally zebrafish, which carry the same p53 gene as humans, can survive low doses of radiation, which causes damage to the DNA, because the gene steps in to repair that damage.
在通常情况下，像人类一样携带相同p 53基因的斑马鱼可以承受小剂量的放射，放射会对DNA造成损坏，而基因会加入对损坏的修复。
