Question 36

Use the following description of an experiment to answer the next question.

A research group hypothesizes that successful infection by HIV depends upon the expression of FSH3, a human gene. They overexpress this gene in T cells (Which HIV normally infects) so that FSH3 protein levels are very high in these cells. In other T-cells, they mutate FSH3 so that none of its encoded protein is made. They then measure HIV infection rate in the control, overexpression, and mutant T cells. The three cultures are otherwise grown in the same way.

What type of experiment is this? (Select all correct answers)

		Observational
		Causative
		Correlative
