DNA is the genetic material that makes up living things, and folic acid plays an important role in the formation of DNA. Jon wants to study the effect of folic acid on DNA formation in microbes. Which statement accurately describe the variables in this study? A. The amount of folic acid and DNA synthesized are both dependent variables. B. The amount of folic acid and DNA synthesized are both independent variables. C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable. D. The amount of folic acid is the dependent variable, and the DNA synthesized is the independent variable. E. The amount of folic acid and DNA synthesized are neither dependent nor independent variables.

The correct answer is - C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.

Explanation:

DNA is the genetic material of most of the living organisms. In this question, Joe wants to study to see the effect of folic acid on the synthesis of the DNA. Folic acid ae the essential nutrients or vitamin for the synthesis of nitrogen bases of the DNA that are purines and pyrimidines. A dependent variable and an independent variable are two important part of any experiment.

A dependent variable is a variable being tested and measured. In the experiment Jon is conducting, the amount of DNA becomes a dependent variable that is being tested and measured in the presence of folic acid.  And folic acid is the independent variable tested to check the formation of DNA in bacteria.

Thus, the correct answer is - C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.
