  2. Nucleotide - Wikipedia

    en.wikipedia.org/wiki/Nucleotide

    This nucleotide contains the five-carbon sugar deoxyribose (at center), a nucleobase called adenine (upper right), and one phosphate group (left). The deoxyribose sugar joined only to the nitrogenous base forms a Deoxyribonucleoside called deoxyadenosine, whereas the whole structure along with the phosphate group is a nucleotide, a constituent of DNA with the name deoxyadenosine monophosphate.

    Genetic genealogy – DNA testing to infer relationships; Haplotype – Group of genes from one parent; Meiosis – Cell division producing haploid gametes; Nucleic acid notation – Universal notation using the Roman characters A, C, G, and T to call the four DNA nucleotides; Nucleic acid sequence – Succession of nucleotides in a nucleic acid

  4. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ...

  5. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Nucleic acid types differ in the structure of the sugar in their nucleotidesDNA contains 2'-deoxyribose while RNA contains ribose (where the only difference is the presence of a hydroxyl group). Also, the nucleobases found in the two nucleic acid types are different: adenine , cytosine , and guanine are found in both RNA and DNA, while ...

  6. STR analysis - Wikipedia

    en.wikipedia.org/wiki/STR_analysis

    STR analysis is a tool in forensic analysis that evaluates specific STR regions found on nuclear DNA. The variable (polymorphic) nature of the STR regions that are analyzed for forensic testing intensifies the discrimination between one DNA profile and another. [3] Scientific tools such as FBI approved STRmix incorporate this research technique.

  7. Nucleic acid sequence - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_sequence

    Nucleic acids consist of a chain of linked units called nucleotides. Each nucleotide consists of three subunits: a phosphate group and a sugar (ribose in the case of RNA, deoxyribose in DNA) make up the backbone of the nucleic acid strand, and attached to the sugar is one of a set of nucleobases.

  8. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/Sequencing

    DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates.

  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.
