  2. Nucleic acid double helix - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_double_helix

    The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...

  3. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    A purine base always pairs with a pyrimidine base (guanine (G) pairs with cytosine (C) and adenine (A) pairs with thymine (T) or uracil (U)). DNA's secondary structure is predominantly determined by base-pairing of the two polynucleotide strands wrapped around each other to form a double helix. Although the two strands are aligned by hydrogen ...

    en.wikipedia.org/wiki/Semiconservative_replication

    During the period of exponential DNA increase at 37 °C, the rate of strand elongation was 749 nucleotides per second. The mutation rate per base pair per round of replication during phage T4 DNA synthesis is 2.4 × 10 −8. [11] Thus, semiconservative DNA replication is both rapid and accurate.

  5. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    Owing to the relatively short nature of the eukaryotic Okazaki fragment, DNA replication synthesis occurring discontinuously on the lagging strand is less efficient and more time-consuming than leading-strand synthesis. DNA synthesis is complete once all RNA primers are removed and nicks are repaired. Depiction of DNA replication at replication ...

  7. Nucleic acid sequence - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_sequence

    The nucleobases are important in base pairing of strands to form higher-level secondary and tertiary structures such as the famed double helix. The possible letters are A , C , G , and T , representing the four nucleotide bases of a DNA strand – adenine , cytosine , guanine , thymine – covalently linked to a phosphodiester backbone.
