A chemical reaction involving a water elimination reaction; a reaction in which a molecule decomposes to two molecules, one smaller than the other. mutagenic DNA base A DNA base that introduces changes in the coding sequence of DNA. Schiff base ...
There are two major classes of chemical probes of DNA structure: those that demonstrate no inherent base preference but are sensitive to DNA geometry, such as groove widths and chirality, and those that are base-specific, detecting bases in distorted regions of the helix. The former bind to DN...
chemical properties of a base. There are four nitrogenous bases that occur in DNA molecules: cytosine, guanine, adenine, and thymine (abbreviated as C, G, A, and T). RNA molecules contain cytosine, guanine, and adenine, but they have a different nitrogenous base, uracil (U) instead of ...
DNA in cells is supercoiled and constrained into loops and this supercoiling and looping influence every aspect of DNA activity. We show here that negative supercoiling transmits mechanical stress along the DNA backbone to disrupt base pairing at specifi
A common method of physical disruption is freezing and grinding samples with a mortar and pestle under liquid nitrogen to provide a powdered material that is then exposed to chemical or enzymatic lysis conditions. Grinders can be simple manual devices or automated, capable of disruption of multiple...
Membrane proteins on the cell surface perform a myriad of biological functions; however, ligand discovery for membrane proteins is highly challenging, because a natural cellular environment is often necessary to maintain protein structure and function. DNA-encoded chemical libraries (DELs) have emerged ...
exists mainly in the nucleus and mitochondria of each cell in an organism. It consists of two long strands linked together in a structure resembling a ladder twisted into a spiral, called adouble helix.Each rung is made up of two chemical bases, callednucleotides,that are joined together by ...
