  2. Upstream and downstream (DNA) - Wikipedia

    en.wikipedia.org/wiki/Upstream_and_downstream_(DNA)

    Due to the anti-parallel nature of DNA, this means the 3' end of the template strand is upstream of the gene and the 5' end is downstream. Some genes on the same DNA molecule may be transcribed in opposite directions. This means the upstream and downstream areas of the molecule may change depending on which gene is used as the reference.

  4. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. [14] The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and ...

  5. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.

  6. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    In DNA double helix, the two strands of DNA are held together by hydrogen bonds. The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. The purines are adenine and guanine ...

  9. Nucleic acid notation - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_notation

    One example of an ambigraphic nucleic acid notation is AmbiScript, a rationally designed nucleic acid notations that combined many of the visual and functional features of its predecessors. [11] Its notation also uses spatially offset characters to facilitate the visual review and analysis of genetic data.
