Which of the following will be curable in next two decades?
Correct answer: B. Cancer
- A. Tuberculosis
- B. Cancer
- C. Poliomyelitis
- D. None of these
Explanation
Cancer may be curable in the next two decades. The completion of the human genome is causing profound changes in the thinking and direction of biomedical research. Cancer is caused by the malfunctioning of genes, either through the activation of cancer-causing oncogenes or through the inactivation of tumor suppressor genes. By comparing the active genes in the tumor to those of normal cells, the genes causing the cancer can be determined. Side by side, there is significant progress in the fields of genetic engineering and biotechnology. All these aspects give us hope that cancer may be curable in the next two decades. Tuberculosis is curable by taking antitubercular drugs, and polio may be on the verge of eradication if the pulse polio program succeeds.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
