Such a quadruplex is described as tetramolecular, reflecting the requirement of four separate strands. The term G4 DNA was originally reserved for these tetramolecular structures that might play a role in meiosis. [5] However, as currently used in molecular biology, the term G4 can mean G-quadruplexes of any molecularity.
DNAzyme research for the treatment of cancer is also underway. The development of a 10-23 DNAzyme that can block the expression of IGF-I (Insulin-like growth factor I, a contributor to normal cell growth as well as tumorigenesis) by targeting its mRNA could be useful for blocking the secretion of IGF-I from prostate storm primary cells ...
G4 theory is an improved modification of the earlier approach G3 theory. The modifications to G3- theory are the change in an estimate of the Hartree–Fock energy limit, an expanded polarization set for the large basis set calculation, use of CCSD(T) energies, use of geometries from density functional theory and zero-point energies , and two ...

A Canadian woman was arrested after trying to smuggle over 20 pounds of methamphetamine through a New Zealand airport, authorities said. The illicit drugs were disguised as Christmas presents, New ...
Hoogsteen pairs have quite different properties from Watson–Crick base pairs.The angle between the two glycosidic bonds (ca. 80° in the A• T pair) is larger and the C1 ′ –C1 ′ distance (ca. 860 pm or 8.6 Å) is smaller than in the regular geometry.
Incubation buffer conditions are altered based on the intended target and desired function of the selected aptamer. For example, in the case of negatively charged small molecules and proteins, high salt buffers are used for charge screening to allow nucleotides to approach the target and increase the chance of a specific binding event.

In late July, Super Micro's auditor at the time, Ernst & Young (EY), raised concerns about the company's governance, transparency and internal control over financial reporting, prompting its board ...
