DNA, or deoxyribonucleic acid, directs cellular function. This is because it contains the genetic instructions used in the development and functioning of all known living organisms and many viruses.

Here's a step-by-step breakdown:

1. DNA is not single stranded. It is a double-stranded molecule, consisting of two biopolymer strands coiled around each other to form a double helix.

2. DNA does not contain six different nucleotide bases. It contains four different nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).

3. DNA directs cellular function. This is the correct answer. The sequence of nucleotides in a DNA molecule determines the sequence of amino acids in a protein, which in turn determines the function of the protein within the cell and the organism.

4. DNA does not contain the base uracil. In DNA, the base thymine is used instead of uracil. Uracil is found in RNA, not DNA.
