Structure of a G-quadruplex. Left: a G-tetrad. Right: an intramolecular G4 complex. [1]: fig1 In molecular biology, G-quadruplex secondary structures (G4) are formed in nucleic acids by sequences that are rich in guanine. [2] They are helical in shape and contain guanine tetrads that can form from one, [3] two [4] or four strands. [5]
First crystal structure of a DNAzyme was reported in 2016. [20] [21] 10-23 core based DNAzymes and the respective MNAzymes that catalyse reactions at ambient temperatures were described in 2018 [22] and open doors for use of these nucleic acid based enzymes for many other applications without the need for heating.

Cells shown with immunostaining observed with a confocal microscope.. Cytomics is the study of cell biology and biochemistry in cellular systems at the single cell level. [1] [2] [3] It combines all the bioinformatic knowledge to attempt to understand the molecular architecture and functionality of the cell system (Cytome).
Ten years after James Watson and Francis Crick published their model of the DNA double helix, [2] Karst Hoogsteen reported [3] a crystal structure of a complex in which analogues of A and T formed a base pair that had a different geometry from that described by Watson and Crick. Similarly, an alternative base-pairing geometry can occur for G ...
A codon table can be used to translate a genetic code into a sequence of amino acids. [1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis.
It is an East Asian haplogroup. [3] Today, haplogroup G is found at its highest frequency in indigenous populations of the lands surrounding the Sea of Okhotsk. [4] [5] Haplogroup G is one of the most common mtDNA haplogroups among modern Ainu, Siberian, Mongol, Tibetan and Central and North Asian Turkic peoples people (as well as among people of the prehistoric Jōmon culture in Hokkaidō).
Structure of mannose in its α-D mannopyranose form. Mannan is a polymer of mannose.. The lectin pathway or MBL pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, [1] in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade.
