Scientists have been experimenting with gene therapy, which often involves the use of bacteria or viruses to deliver new or modified genes to cells. These scientists believe gene therapy can be used to treat inherited diseases, but it is not yet in wide use even though many people have studied it. Which statement best describes gene therapy?
Answer
A
The idea has not yet achieved scientific consensus.
B
The idea has gained scientific consensus against its use.
C
The idea takes too long to test to develop scientific consensus.
D
The idea is supported by most scientists, but a vocal minority disagrees.
Explanation
Gene therapy is still being studied, and the question says it is not yet in wide use. That suggests its effectiveness and appropriate uses have not yet reached scientific consensus. This does not mean scientists have reached consensus against using it; continued research is aimed at evaluating it.
