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] As a substituent it takes the form of the prefix adenylyl-. [2]
Transcription-mediated amplification ( TMA) is an isothermal (performed at constant temperature), single-tube nucleic acid amplification system utilizing two enzymes, RNA polymerase and reverse transcriptase . "Amplification" means creating many more copies of a strand of nucleic acid than was present at first, in order to readily detect it or ...
The Association for Molecular Pathology (abbreviated AMP) is a professional association of individuals serving patients through molecular diagnostics testing. Founded in 1995, the Association has more than 2,800 members in over 50 countries. [1] Molecular diagnostics is one of the fastest growing fields of health care.
Natural DNA amplification. DNA replication is a natural form of copying DNA with the amount of genes remaining constant. However, the amount of DNA or the number of genes can also increase within an organism through gene duplication, a major mechanism through which new genetic material is generated during molecular evolution.
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 ...
A nucleoside consists simply of a nucleobase (also termed a nitrogenous base) and a five-carbon sugar ( ribose or 2'-deoxyribose) whereas a nucleotide is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups. In a nucleoside, the anomeric carbon is linked through a glycosidic bond to the N9 of a purine or the N1 of a ...
In the assay, branched DNA is mixed with a sample to be tested. The detection is done using a non-radioactive method and does not require preamplification of the nucleic acid to be detected. The assay entirely relies on hybridization. Enzymes are used to indicate the extent of hybridization but are not used to manipulate the nucleic acids.
Nucleic acid metabolism is a collective term that refers to the variety of chemical reactions by which nucleic acids ( DNA and/or RNA) are either synthesized or degraded. Nucleic acids are polymers (so-called "biopolymers") made up of a variety of monomers called nucleotides. Nucleotide synthesis is an anabolic mechanism generally involving the ...
