Error studies for DNA data storage
Due to its large storage capacity and preservation ability, Deoxyribonucleic Acid (DNA) has become an attractive medium to store the increasing amount of information present today. Various research has been conducted to examine more ways to tap on the potential of DNA storage. However, due to the co...
