    en.wikipedia.org/wiki/Who_We_Are_and_How_We_Got_Here

    Who We Are and How We Got Here is a 2018 book on the contribution of genome-wide ancient DNA research to human population genetics by the geneticist David Reich.He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world.

  3. Molecular Structure of Nucleic Acids: A Structure for ...

    en.wikipedia.org/wiki/Molecular_Structure_of...

    The two base-pair complementary chains of the DNA molecule allow replication of the genetic instructions. The "specific pairing" is a key feature of the Watson and Crick model of DNA, the pairing of nucleotide subunits. [5] In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T and C:G pairs ...

  4. 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.

  5. Personal genomics - Wikipedia

    en.wikipedia.org/wiki/Personal_genomics

    Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing.

  6. 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.

  8. Intercalation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Intercalation_(biochemistry)

    Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas). In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning.

  9. Agarose gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Agarose_gel_electrophoresis

    However, the migration of DNA molecules in solution, in the absence of a gel matrix, is independent of molecular weight during electrophoresis. [ 4 ] [ 20 ] The gel matrix is therefore responsible for the separation of DNA by size during electrophoresis, and a number of models exist to explain the mechanism of separation of biomolecules in gel ...
