Q. With reference to Malaria, consider the following statements;
1.It is caused by the bite of the female mosquito whenever it bites the human.
2.‘Gene drive’ technology can help in controlling Malaria.
3.Mosquirix, the malaria vaccine, offers protection against all kinds of malarial parasites.
Which of the statements given above is/are correct?
Answer: C
Notes:
Statement 1 is incorrect: It is caused by the bite of the female Anopheles mosquito (vector) if the mosquito itself is infected with a malarial parasite.
Statement 2 is correct: ‘Gene drive’ technology can help in controlling Malaria. Gene drive would cause the anti-parasite genetic modification to be preferentially inherited, making it spread more widely among any natural population of mosquitoes.
Statement 3 is incorrect: Mosquirix, the malaria vaccine, offers no protection against P vivax malaria, which is prevalent in many countries outside Africa.
