How many different 6-mer sequences of DNA are there? (Hint: There are 16 possible dinucleotides and 64 possible trinucleotides). We can quantify the information-carrying capacity of nucleic acids in the following way. Each position can be one of four bases, corresponding to two bits of information (22 = 4). Thus, a chain of 5100 nucleotides corresponds to 2 X 5100 = 10200 bits or 1275 bytes (1 byte = 8 bits). How many bits of information are stored in a 6-mer DNA sequence?
