Independent variable can be defined as a variable which can be changed or manipulated in an experimental set up to record and observe it's effect on the dependent variable. A dependent variable is a variable which is dependent on the independent variable. The outcome of the dependent variable is the result of the experiment. A controlled variable is a variable which does not change in a reaction, and kept as a constant.

B. The ddNTPs lack a 3′ hydroxyl group.
Explanation:
Dideoxynucleotides is a family of inhibitors of the DNA polymerase, its official name is 2',3' dideoxynucleotides but they are commonly called ddNTPs. One of the main characteristics of this compound is the absence of the 3'-hydroxyl group in the deoxyribose, due to the absence of this group, it is impossible to form a phosphodiester bond between nucleotides and the DNA synthesis is stopped.
