  2. 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.

  3. 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.

  4. 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 ...

    The DNA sequence may be aligned with other DNA sequences to ... This field of phylogenetics is a powerful tool in evolutionary biology. If DNA sequences within a ...

  6. 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]

  7. Read (biology) - Wikipedia

    en.wikipedia.org/wiki/Read_(biology)

    In DNA sequencing, a read is an inferred sequence of base pairs (or base pair probabilities) corresponding to all or part of a single DNA fragment. A typical sequencing experiment involves fragmentation of the genome into millions of molecules, which are size-selected and ligated to adapters.

  8. 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 ...

  9. Gene - Wikipedia

    en.wikipedia.org/wiki/Gene

    The molecular gene definition is more commonly used across biochemistry, molecular biology, and most of genetics—the gene that is described in terms of DNA sequence. [1] There are many different definitions of this gene—some of which are misleading or incorrect.
