176. As a result of the ground-breaking work of Barbara McClintock,many secientists 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

og 解释：Choices 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. 那么正确答案E代表了一个细胞中的全部还是部分基因呢？
