  2. Artificial gene synthesis - Wikipedia

    en.wikipedia.org/wiki/Artificial_gene_synthesis

    While traditional nucleic acid synthesis only uses 4 base pairs - adenine, thymine, guanine and cytosine, oligonucleotide synthesis in the future could incorporate the use of unnatural base pairs, which are artificially designed and synthesized nucleobases that do not occur in nature.

  3. Contig - Wikipedia

    en.wikipedia.org/wiki/Contig

    A contig (from contiguous) is a set of overlapping DNA segments that together represent a consensus region of DNA. [1] In bottom-up sequencing projects, a contig refers to overlapping sequence data (); [2] in top-down sequencing projects, contig refers to the overlapping clones that form a physical map of the genome that is used to guide sequencing and assembly. [3]

  4. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Nucleic acids RNA (left) and DNA (right). Nucleic acids are large biomolecules that are crucial in all cells and viruses. [1] They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid ...

  5. Transcription activator-like effector nuclease - Wikipedia

    en.wikipedia.org/wiki/Transcription_activator...

    The DNA binding domain contains a repeated highly conserved 33–34 amino acid sequence with divergent 12th and 13th amino acids. These two positions, referred to as the Repeat Variable Diresidue (RVD), are highly variable and show a strong correlation with specific nucleotide recognition.

  6. Oligonucleotide - Wikipedia

    en.wikipedia.org/wiki/Oligonucleotide

    Oligonucleotides are short DNA or RNA molecules, oligomers, that have a wide range of applications in genetic testing, research, and forensics.Commonly made in the laboratory by solid-phase chemical synthesis, [1] these small fragments of nucleic acids can be manufactured as single-stranded molecules with any user-specified sequence, and so are vital for artificial gene synthesis, polymerase ...

  7. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life. The two DNA strands are known as polynucleotides as they are composed of simpler monomeric units called nucleotides.

  8. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    The nucleic acids constitute one of the four major macromolecules essential for all known forms of life. RNA is assembled as a chain of nucleotides . Cellular organisms use messenger RNA ( mRNA ) to convey genetic information (using the nitrogenous bases of guanine , uracil , adenine , and cytosine , denoted by the letters G, U, A, and C) that ...

  9. Molecular models of DNA - Wikipedia

    en.wikipedia.org/wiki/Molecular_models_of_DNA

    From the very early stages of structural studies of DNA by X-ray diffraction and biochemical means, molecular models such as the Watson-Crick nucleic acid double helix model were successfully employed to solve the 'puzzle' of DNA structure, and also find how the latter relates to its key functions in living cells.
