Visualization of nucleic acid sequences
A system and process are provided for analyzing nucleic acid data. An example process can include receiving nucleic acid data including a set of sequence data. The nucleotides of the sequence data can be assigned numerical values. Using these assigned values, partial sums can be calculated for each position in the set of sequence data. The resulting sums can then be displayed in form of Charts or Maps which is so called sequence spectrum to make it easy to navigate and analyze the whole data set. In some examples, patterns or similar/identical sequence segments can be identified within a single set of sequence data or between different sets of sequence data in the spectrum.

Board game for teaching dna concepts
A board game for teaching pattern recognition. In one embodiment, the present invention teaches DNA concepts wherein patterns identified on playing cards represent a sequential biocode pattern and a plurality of game pieces represent biocodes differentiated by shape and color. Corresponding biocodes represent base pairs bound together to form the helix structure of DNA. Preferably, pattern recognition is taught utilizing a simple story line such as deep-space travelers having to repair a spaceship, by having to match a sequential pattern with game pieces (biocodes) to retrieve a spaceship part, in order to escape a distant planet.

Method and apparatus for encoding information units in code word sequences avoiding reverse complementarity
A method (100) and an apparatus (200) for encoding information in code word sequences are described which avoid reverse complementarity of the sequences, making them suitable for synthesizing nucleic acid strands. Multiple codes are provided (102), consisting of a same amount of corresponding code words. No word belongs to more than one code. Each code could completely encode all information units which are encoded using code word sequences generated from the codes. Generating (105) a sequence comprises: selecting (106), from code words of a code, a next code word to be appended to the sequence; appending (108) the next code word if a concatenation of the sequence and the next code word does not contain a reverse complementary of any code symbol sequence that at least partly contains the next code word; and otherwise (109) selecting a corresponding next code word from a different code and repeating the appending.
