176. As a result of the ground-breaking work of

Barbara McClintock, many scientists now believe that all of the information encoded in 50.000 to 100.000 of the different genes found in a human cell are contained in merely three percent of the cell's DNA.

(A) 50,000 to 100,000 of the different genes found in a human cell are contained in merely

(B) 50,000 to 100,000 of the human cell's different genes are contained in a mere

(C) the 50,000 to 100,000 different genes found in human cells are contained in merely

(D) 50,000 to 100,000 of human cells' different genes is contained in merely

(E) the 50,000 to 100,000 different genes found in a human cell is contained in a mere

特指那些genes

This question poses two problems: subject-verb agreement and accuracy of expression. Choice E, the best answer, states the matter clearly and grammatically. The subject, all of the information, must be taken as singular because the mass noun information is singular. Choices A, B, and C all mistake the number of the subject and incorrectly use the plural verb are contained. A, B, and D do not make it clear whether 50,000 to 100,000 represents all or a fraction of the genes in a cell. C and D, by referring to cells in the plural, do not make it clear whether the number mentioned is to be found in each individual cell or in a collection of cells.

我的问题是

e中前面加the 和不加意思有什么不一样呢？哪个是指5000-100000是全部的genes，哪个是指只是一部分

如果两个意思不一样的话，选了e难道没有改变原文的意思么？？

这道题的重点不在这里，而在这里：

稍微有一点生物常识的话就知道，人类的任何一个细胞里，就已经把这整个人所有的基因包括在里面了（这就是“克隆”技术的“单细胞繁殖”的理论基础。。。呵呵）。而题目中还说到，所有这些基因信息仅仅占这个细胞DNA的很小的一个部分（题目中说是3％）。从这点出发，就可以排除其他所有的错误选项了。
