A procedure for storage and retrieval of Digital information in DNA strings is discussed by constructing an error correction code which is capable of correcting indel errors and maintaining the stability of DNA strings. For correction of indel errors, Varshamov-Tenengolts algorithm is used. To maintain the stability of DNA code, Reverse-complementary property, and GC-content constraints are implemented by appropriate choices of group homomorphisms. Code for any desired length(n) can be created using the construction methods presented in this paper. The code's reverse complement distance is calculated using the value of n.
