1问题蔡华瑞[广东省廉江市廉江中学(524400)]将R型菌的DNA与S型菌混合注入小鼠体内,会得到R型菌吗?2讨论任智安[北京市通州区永乐店中学(101 105)]如果要得到R型菌,肺炎双球菌的表面上必须要失去荚膜。理论上可行,基因重组时只要破坏荚膜相关基因导致基因失活即可。吴志强[安徽省芜湖市第十二中学(241003)]为什么S型菌的DNA能够让R型菌转化?因为S型
1 question Cai Huarui [Lianjiang Middle School of Lianjiang City, Guangdong Province (524400]] R type bacteria DNA mixed with S-type bacteria injected into the body of mice, will get R-type bacteria? 2 Discussion Ren Zhi’an [Tongzhou District, Beijing Yongledian Middle School (101 105)] The capsule must be lost on the surface of pneumococci if R type bacteria are to be obtained. Theoretically feasible, as long as genetic disruption of capsular related genes lead to gene inactivation can be. Wu Zhiqiang [Wuhu City, Anhui Province, the twelfth secondary school (241003)] Why S-type bacteria DNA can make R-type transformation? Because S
