However, the success rate for accurately inserting the gene into the target chromosome and inducing its expression is not high. The research team led by Tsai had to repeatedly assemble and test combinations of gene segments before finally successfully breeding a transgenic fish whose entire body emitted a green glow.
不過，外來基因準確嵌入染色體中並表現出性狀的成功機率不高，蔡懷楨所帶領的研究團隊經過不斷的嘗試，構築無數基因片段的組合後，才終於孵育出全身散發出綠色螢光的基因轉殖魚。
