Which of the following is not contained in the genetically modified maize?
A genetically modified (GM) maize fortified with three vitamins has been created by European researchers. The modifications make the growing maize, or corn, produce large amounts of [25B] beta carotene and precursors of vitamin C and folic acid.
The development marks the first time any plant has been engineered to make more than one vitamin.
The creators argue the crop could help improve diets in poorer nations, but anti-GM campaigners are skeptical.
选项
A、Beta carotene.
B、Precursors of vitamin B.
C、Precursors of vitamin C.
D、Folic acid.
答案
B
解析
新闻中提到,新的转基因玉米包含beta carotene and precursors of vitamin C and folic acid,而并没有Precursors of vitamin B。所以答案为[B]。
