Question Details:
DNA is mad up of nucleotides. Each nucleotide can contain any one of these nitrogenous bases: A (adenine), G (guanine), C (cytosine), T (Thymine). If one of these four bases (A,G,C,T) must be selected three times to form a linear triplet, how many different triplets are possible? Not all four bases can be selected for each of the three components of the triplet.
