  2. DNA sequencing theory - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing_theory

    DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA, otherwise known as DNA sequencing. The practical aspects revolve around designing and optimizing sequencing projects (known as "strategic genomics"), predicting project performance ...

  3. 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.

  4. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...

  5. Nucleic acid sequence - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_sequence

    DNA sequencing is the process of determining the nucleotide sequence of a given DNA fragment. The sequence of the DNA of a living thing encodes the necessary information for that living thing to survive and reproduce. Therefore, determining the sequence is useful in fundamental research into why and how organisms live, as well as in applied ...

  6. Southern blot - Wikipedia

    en.wikipedia.org/wiki/Southern_blot

    The DNA fragments are transferred out of the gel or matrix onto a solid membrane, which is then exposed to a DNA probe labeled with a radioactive, fluorescent, or chemical tag. The tag allows any DNA fragments containing complementary sequences with the DNA probe sequence to be visualized within the Southern blot. [1]

  7. Molecular genetics - Wikipedia

    en.wikipedia.org/wiki/Molecular_genetics

    The discovery of DNA as the blueprint for life and breakthroughs in molecular genetics research came from the combined works of many scientists. In 1869, chemist Johann Friedrich Miescher, who was researching the composition of white blood cells, discovered and isolated a new molecule that he named nuclein from the cell nucleus, which would ultimately be the first discovery of the molecule DNA ...

  9. Low copy repeats - Wikipedia

    en.wikipedia.org/wiki/Low_copy_repeats

    The repeats, or duplications, are typically 10–300 kb in length, and bear greater than 95% sequence identity. Though rare in most mammals, LCRs comprise a large portion of the human genome owing to a significant expansion during primate evolution. [1] In humans, chromosomes Y and 22 have the greatest proportion of SDs: 50.4% and 11.9% ...
