Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Malaria is a disease caused by parasites that reproduce within red blood cells. Malaria can cause fever, chills, nausea, flu-like symptoms, and in some cases, coma and death. This disease is prevalent in warm climates, especially South America, Africa, and the southern portions of Asia.Sickle-cell anemia is a genetic disorder that causes red blood cells to change shape when they are deoxygenated. The resultant sickle-shaped blood cells can get stuck in blood vessels and cause damage and pain. This disease is also prevalent in South America, Africa, and Asia.Lately, it was discovered that people who carry the sickle-cell trait heterozygously are resistant to malaria. How could biotechnology best use this infomation to help people living in these areas?
A
Biotechnology could be used to make the climate cooler so that mosquitoes are unable to breed.
B
Biotechnology could be used to eliminate all sickle-cell genes.
C
Biotechnology could be used to alter the mosquito DNA.
D
Biotechnology could be used to insert malaria resistant genes into humans without causing sickle cell anemia.
