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 ...
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 ...
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...
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 ...

我们今天知道,UNG是负责碱基切除修复(base excision repair,BER)的一大家族蛋白质的基本成员。发现UNG依赖于对作为自由碱基从体外DNA中酶促释放尿嘧啶的仔细分析。林德尔证明这种酶特异性作用于DNA,而不作用于脱氧单核苷酸或任何形式的RNA。他还提出,在这个过程中DNA骨架保持完整,这暗示了另一类酶,即脱嘌呤/脱嘧啶...

Chemical principles of DNA sequence recognition and gene regulation V.2 Review of DNA structure V.2.1 B-DNA, major and minor grooves Double-stranded DNA can adopt different types of structures depending on the base sequence, solution conditions, and the presence of other molecules, such as protei...
DNA Repair refers to the cellular processes involved in restoring the normal base-pair sequence and structure of damaged DNA. It includes six primary pathways with biochemical events for sensing, excision, and restoring the DNA sequence. AI generated definition based on: The Molecular Basis of Cance...
