DNA computing is one interdisciplinary research field that is growing fast as it can simulate the biomolecular structure of DNA and compute using this DNA sequence. At first, Adleman showed that DNA could solve a problem. He cracked a complex problem using the Hamiltonian path problem, and this approach has been extended by Lipton, who can solve another NP-complete problem. Many researchers are working to produce a computer based on DNA molecules to replace or beneficially complement a silicon-based computer. The primary function of DNA is to transmit data, and they can process this data simultaneously. Data is encoded in a DNA strand form in this DNA computing. It has several merits such as high storage capacity, faster speed because of parallelism, and low power consumption. A mix of 1018 DNA strands could operate 104 times faster than today’s advanced computer, which is incredible.
