  2. Adenosine monophosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_monophosphate

    Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide.AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.It is an ester of phosphoric acid and the nucleoside adenosine. [1]

  3. Ribonucleotide - Wikipedia

    en.wikipedia.org/wiki/Ribonucleotide

    DNA is defined by containing 2'-deoxy-ribose nucleic acid while RNA is defined by containing ribose nucleic acid. [1] In some occasions, DNA and RNA may contain some minor bases. Methylated forms of the major bases are most common in DNA. In viral DNA, some bases may be hydroxymethylated or glucosylated.

  4. Arecibo message - Wikipedia

    en.wikipedia.org/wiki/Arecibo_message

    The "Hampshire pattern" or "Chilbolton Code formation" or "Arecibo answer" was a crop circle that appeared in 2001 near the Chilbolton radio telescope in Hampshire, UK, which echoed the visual representation and most of the information from the original Arecibo message with some significant differences including location/origin, DNA ...

  5. Nucleoside triphosphate - Wikipedia

    en.wikipedia.org/wiki/Nucleoside_triphosphate

    A nucleoside triphosphate is a nucleoside containing a nitrogenous base bound to a 5-carbon sugar (either ribose or deoxyribose), with three phosphate groups bound to the sugar. [1] They are the molecular precursors of both DNA and RNA, which are chains of nucleotides made through the processes of DNA replication and transcription. [2]

  6. Nucleotide base - Wikipedia

    en.wikipedia.org/wiki/Nucleotide_base

    DNA and RNA also contain other (non-primary) bases that have been modified after the nucleic acid chain has been formed. In DNA, the most common modified base is 5-methylcytosine (m 5 C). In RNA, there are many modified bases, including those contained in the nucleosides pseudouridine (Ψ), dihydrouridine (D), inosine (I), and 7-methylguanosine ...

  7. The Answer Man - Wikipedia

    en.wikipedia.org/wiki/The_Answer_Man

    The offices of The Answer Man were across the street from the New York Public Library, a source for many of the answers. The Answer Man is a United States 15-minute radio program that aired from 1937 to 1956 on the Mutual Broadcasting System and also in syndication. [1] It was broadcast late Sunday evening on some stations.

  8. Nucleic acid quantitation - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_quantitation

    For pure DNA, A 260/280 is widely considered ~1.8 but has been argued to translate - due to numeric errors in the original Warburg paper - into a mix of 60% protein and 40% DNA. [6] The ratio for pure RNA A 260/280 is ~2.0. These ratios are commonly used to assess the amount of protein contamination that is left from the nucleic acid isolation ...

  9. Primer extension - Wikipedia

    en.wikipedia.org/wiki/Primer_extension

    It is usually done so by comparing its location on the gel with the DNA sequence (e.g. Sanger sequencing), preferably by using the same primer on the DNA template strand. The exact nucleotide by which the transcription starts at can be pinpointed by matching the labelled extended primer with the marker nucleotide, who are both sharing the same ...
