Alu Elements definition: The Alu sequence family (named for the restriction endonuclease cleavage enzyme Alu I) is the most highly repeated interspersed repeat element in humans (over a million copies). It is derived from the 7SL RNA component of the SIGNAL RECOGNITION PARTICLE and contains an RNA polymerase III promoter. Transposition of this element into coding and regulatory regions of genes is responsible for many heritable diseases.
DNA Transposable Elements definition: Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.
Elements definition: Substances that comprise all matter. Each element is made up of atoms that are identical in number of electrons and protons and in nuclear charge, but may differ in mass or number of neutrons.
element definition: fundamental chemical units of which all matter at or above the atomic level is composed; each element is made up of atoms that are identical in number of electrons and protons and in nuclear charge, but may differ in mass or number of neutrons; such varieties of an element are isotopes.
Element definition: A substance whose atoms all have the same atomic number, that cannot be divided into simpler substances, and that singly or in combination constitute all matter.
Elements, Radioactive definition: Elements which exhibit atomic emission due to natural or artificial nuclear transformation. These elements spontaneously undergo radioactive decay.
genetic enhancer element definition: cis-acting DNA sequences which can increase transcription of genes; enhancers can usually function in either orientation and at various distances from a promoter.
Enhancer Elements, Genetic definition: Cis-acting DNA sequences which can increase transcription of genes. Enhancers can usually function in either orientation and at various distances from a promoter.
Halogens definition: A family of nonmetallic, generally electronegative, elements that form group 17 (formerly group VIIa) of the periodic table.
halogen definition: elements of Group VII of the periodic table.
