国内英语资讯:China Focus: Chinese scientists perform genetic surgery to create first single-chromosome ye
"The survival rate of spores produced by a natural yeast strain is 98 percent, while that of ours is 87.5 percent. The gap is not big," Qin said.
The paper also said that Jef Boeke, a geneticist at New York University, and his team submitted their outcome for similar research. They condensed the yeast genome into a pair of chromosomes, but could not fuse the pair into one.
One explanation for the difference is that Qin's team removed 19 repetitive stretches of DNA. Qin suggested these sequences might have interfered with the mechanism that cells use to fuse two chromosomes into one.
The two teams worked independently from each other.
