In DNA splicing systems, restriction enzymes and ligases cleave and recombine DNA molecules based on the cleavage pattern of the restriction enzymes. The set of molecules resulting from the splicing system depicts a splicing language. In this research, an algorithm for DNA splicing systems is developed using C++ visual programming. The splicing languages which have been characterised through some theorems based on the crossings and sequences of the restriction enzymes, are generated as the output from this computation. In order to generate the splicing languages, the algorithm detects and calculates the number of cutting sites of the restriction enzymes found in the initial molecules, determines whether the sequence of restriction enzyme is a palindrome or not, and if the restriction enzymes have the same or different crossings. The results from this research depict the splicing languages obtained from the manual computations, which contributes to the development of computational software in DNA computing.

In DNA splicing system, the potential effects of sets of restriction enzymes and a ligase that allow DNA molecules to be cleaved and reassociated to produce further molecules are studied.  A splicing language depicts the molecules resulting from a splicing system.  In this research, a C++ programming code for DNA splicing system with one palindromic restriction enzyme for one and two (non-overlapping) cutting sites is developed.  A graphical user interface, GUI is then designed to allow the user to insert the initial DNA string and restriction enzymes to generate the splicing languages which are the result of the computation of the C++ programming.  This interface displays the resulting splicing languages, which depict the results from in vitro experiments of the respective splicing system.  The results from this research simplify the lenghty manual computation of the resulting splicing languages of DNA splicing systems with one palindromic restriction enzyme.

In DNA splicing system, DNA molecules are cut and recombined with the presence of restriction enzymes and a ligase. The splicing system is analyzed via formal language theory where the molecules resulting from the splicing system generate a language which is called a splicing language. In nature, DNA molecules can be read in two ways; forward and backward. A sequence of string that reads the same forward and backward is known as a palindrome. Palindromic and non-palindromic sequences can also be recognized in restriction enzymes. Research on splicing languages from DNA splicing systems with palindromic and non-palindromic restriction enzymes have been done previously. This research is motivated by the problem of DNA assembly to read millions of long DNA sequences where the concepts of automata and grammars are applied in DNA splicing systems to simplify the assembly in short-read sequences. The splicing languages generated from DNA splicing systems with palindromic and nonpalindromic restriction enzymes are deduced from the grammars which are visualised as automata diagrams, and presented by transition graphs where transition labels represent the language of DNA molecules resulting from the respective DNA splicing systems.

Abstract Motivation Programmed DNA elimination (PDE) plays a crucial role in the transitions between germline and somatic genomes in diverse organisms ranging from unicellular ciliates to multicellular nematodes. However, software specific for the detection of DNA splicing events is scarce. In this paper, we describe Accurate Deletion Finder (ADFinder), an efficient detector of PDEs using high-throughput sequencing data. ADFinder can predict PDEs with relatively low sequencing coverage, detect multiple alternative splicing forms in the same genomic location and calculate the frequency for each splicing event. This software will facilitate research of PDEs and all down-stream analyses. Results By analyzing genome-wide DNA splicing events in two micronuclear genomes of Oxytricha trifallax and Tetrahymena thermophila, we prove that ADFinder is effective in predicting large scale PDEs. Availability and implementation The source codes and manual of ADFinder are available in our GitHub website: https://github.com/weibozheng/ADFinder. Supplementary information Supplementary data are available at Bioinformatics online.
