  2. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    Their corresponding X-ray diffraction and scattering patterns are characteristic of molecular paracrystals with a significant degree of disorder. [52] [53] Compared to B-DNA, the A-DNA form is a wider right-handed spiral, with a shallow, wide minor groove and a narrower, deeper major groove. The A form occurs under non-physiological conditions ...

  3. 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.

  4. Repeated sequence (DNA) - Wikipedia

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

    Repeated sequences (also known as repetitive elements, repeating units or repeats) are short or long patterns that occur in multiple copies throughout the genome.In many organisms, a significant fraction of the genomic DNA is repetitive, with over two-thirds of the sequence consisting of repetitive elements in humans. [1]

  5. 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 ...

  6. A-DNA - Wikipedia

    en.wikipedia.org/wiki/A-DNA

    A-DNA is broader and more compressed along its axis than B-DNA. [2] [3] The identifiable characteristic of A-DNA X-ray crystallography is the hole in the center. [2] A-DNA has a C3'-endo pucker, which refers to the C3' carbon in the furanose ring being below the sugar plane.

  7. Introduction to genetics - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_genetics

    DNA can be copied very easily and accurately because each piece of DNA can direct the assembly of a new copy of its information. This is because DNA is made of two strands that pair together like the two sides of a zipper. The nucleotides are in the center, like the teeth in the zipper, and pair up to hold the two strands together.

  8. DNA synthesis - Wikipedia

    en.wikipedia.org/wiki/DNA_synthesis

    DNA synthesis is the natural or artificial creation of deoxyribonucleic acid (DNA) molecules. DNA is a macromolecule made up of nucleotide units, which are linked by covalent bonds and hydrogen bonds, in a repeating structure.

  9. Nuclear DNA - Wikipedia

    en.wikipedia.org/wiki/Nuclear_DNA

    Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells.Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin.
