Abstract

We define three operations on strings and languages suggested by the process of gene assembly in hypotrichous ciliates. This process is considered to be a prime example of DNA computing in vivo. This paper is devoted to some computational aspects of these operations from a formal language point of view. The closure of the classes of regular and context-free languages under these operations is settled. Then, we consider theld macronuclear language of a given language L, which consists of all ld- macronuclear strings obtained from the strings of L by iteratively applying the loop-direct repeat-excision. Finally, we discuss some open problems and further directions of research.
