A) 12
B) 16
C) 20
D) 64
E) 256
Nucleic Acid Bases
The parts of DNA and RNA molecules that carry genetic information, specifically adenine, thymine (in DNA), cytosine, guanine, and uracil (in RNA).
Three-Base Combinations
Sequences of three nucleotide bases in DNA or RNA, known as codons, which specify the addition of a specific amino acid to a growing polypeptide chain during protein synthesis.

Final Answer :
D
Explanation :
There are four nucleic acid bases (adenine, cytosine, guanine, and thymine in DNA; uracil replaces thymine in RNA). For each position in a three-base combination, there are four possibilities, leading to 4^3 = 64 different combinations.
