The distribution of the units digit of consecutive primes in base 5, base 8, base 10 and base 12 were studied. The representation and visualization method for DNA sequences was adopted. For small k-number the frequency of appearance was examined directly. The 1-number distribution was uniform and the 2-number distribution showed a deficiency in repeated digits. The base 8 was observed to be more regular than base 8 and base 12. The range of frequency of the prime number was found to be larger in base 8 and the same for base 10 and base 12 on comparison of the prime number sequence to the biased -random sequence.
