How is it that DNA "knows" which specific amino acids, proteins, or enzymes to create?
A) The number of chromosomes that makes up the DNA strand determines this outcome.
B) The length of the DNA strand, determined by the number of genes on the strand, produces the specific outcome.
C) The combination of XX and XY chromosomes in the DNA strand determines this outcome.
D) The order in which the four nucleotide bases occur in the DNA strand results in the specific production outcomes.

The order in which the four nucleotide bases occur in the DNA strand (adenine, thymine, guanine, and cytosine) determines the sequence of codons, which in turn determines the specific amino acid sequence for protein synthesis. Each codon codes for a specific amino acid, and the order of the codons determines the order of amino acids in a protein. Therefore, the sequence of the DNA strand ultimately determines which specific amino acids, proteins, or enzymes are created.
