Dynamic model of the dna molecule

The invention is a dynamic model of the DNA molecule. The invention includes a multiplicity of physical representations of the four nucleotides. Each physical representation is comprised of T-shaped members having an elongate body attached to a flexible planar member. The invention also includes a first joint, located at an end of the elongate bodies which physically represent the Adenine base and the Thymine base, for attaching the Adenine base to the Thymine base, wherein the joint is rotatable. The invention further includes a second joint, located at an end of the elongate bodies which physically represent the Guanine base and the Cytosine base, for attaching the Guanine base to the Cytosine base, wherein the joint is rotatable. Lastly, the invention includes a connections between the nucleotides and the flexible planar member. The flexible planar member physically represents the sugar-phosphate structure of the DNA molecule. Preferably the elongate bodies are made-up of a rigid material, and the flexible planar members are made-up of vinyl. It is also preferred that the joints and connections are easily engaged and disengaged.CROSS-REFERENCE TO A RELATED APPLICATIONThis application is based on a provisional application Ser.

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.

Analysis of arrays

Techniques and equipment are provided, including computer-related software and hardware, for analyzing biological events on multiple-spot arrays for chemical, biological, or biochemical analysis. In one arrangement, techniques and equipment are provided for analyzing nucleotide sequences of nucleic acid molecules, e.g., using multiple probes per spot of an array. Arrays can be provided in which multiple probes exist on multiple spots, and where analysis of whether a particular target molecule bound to a particular spot does not necessarily provide information on what probe the target bound to. The invention provides techniques for analyzing biological events in the form of, for example, deconvolution of binding data.
