Dna structure and manipulation 60 speed of a dna computer can outshine that of a conventional electronic computer, even though the execution time of a single dna molecule reaction is relatively slow. The dna double helix polymer of nucleic acid, held together by nucleotides which base pair together in b-dna, the most common double helical structure found in nature, the double helix is right-handed with about 10–105 base pairs per turn the double helix structure of dna contains a major groove and minor groove. Examining x-ray images of dna revealed that the molecule had a helical, or spiral, shape data from another lab indicated that there is a one-to-one ratio between adenine and thymine the lab also demonstrated that there is a one-to-one ratio between guanine and cytosine. In double-stranded dna, the nitrogenous bases pair up adenine pairs with thymine (a-t) and guanine pairs with cytosine (g-c) the shape of dna resembles that of a spiral staircase in this double helical shape, the sides of the staircase are formed by strands of deoxyribose sugar and phosphate molecules.
Dna in nature and medical science research concept as a group of flying birds shaped as a double helix as a biotechnology and health care biology technology symbol for gene chemistry and genetic medicine. In the field of animal and human genetic engineering the spiral staircase molecule over genetic engineering, an essay about genetics and such . Within a dna molecule, there are specific nucleotide binding patterns, a phenomenon called “complementary base pairing” specific pyrimidine nucleotides can only bind to specific purine bases: cytosine binds to guanine via three hydrogen bonds and adenine binds to thymine via hydrogen bonds.
