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 to100,000 of the different genes found in a human cell are contained in merely (B) 50,000 to100,000 of the human cell's different genes are contained in a mere (C) the 50,000 to100,000 different genes found in human cells are contained in merely (D) 50,000 to100,000 of human cell's different genes is contained in merely (E) the 50,000 to100,000 different genes found in a human cell is contained in a mere
The usage of the definite article ‘the’ is one key to the right answer. The text means to say that the each human cell contains in all some 50,000 to 100,000 genes. (That is all, no more). This entirety is brought out by the use of the definite article. Choices which do not use ‘the’ mean that only 50,000 to 100,000 thousand genes of possibly a higher number than that are contained in a cell. This critical difference leaves us only with choices C and E. Information is a singular noun and therefore ‘is contained’ is the suitable verb. E is the choice.
