On DNA codes from a family of chain rings

In this work, we focus on reversible cyclic codes which correspond to reversible dna codes or reversible-complement dna codes over a family of finite chain rings, in an effort to extend what was done by yildiz and siap in [20]. the ring family that we have considered are of size 2^2k , k = 1; 2; and we match each ring element with a dna 2^k-1-mer. we use the so-called u^2- adic digit system to solve the reversibility problem and we characterize cyclic codes that correspond to reversible-complement dna-codes. we then conclude our study with some examples.
