WebJul 30, 2024 · The most frequent damage type is the cis-syn cyclobutane pyrimidine dimer (CPD), which arises after absorption of photons by DNA bases and occurs through the formation of electronic excited states. Any two adjacent pyrimidine bases can dimerize via their 5,6 double bonds. WebApr 28, 2024 · Ultraviolet light is a physical mutagen and can induce mutation. Ultra violet radiation (254 nm) causes formation of pyrimidine dimers (cyclobutane ring), when two pyrimidine bases occurs together in single strand of DNA. Thymine dimer is most common one but cytosine dimer as well as thymine-cytosine may also occurs.
WebFeb 16, 2016 · A pyrimidine is an organic compound known as an aromatic heterocyclic compound and has the molecular formula of C 4 H 4 N 2. Heterocyclic compounds are … WebDNA has four types of nitrogenous bases: Adenine, Guanine, Thymine, and Cytosine. Adenine and guanine are purines while thymine and cytosine are pyrimidines. Two bases link by a hydrogen bond and form base pairs. Base pairs in DNA are Adenine - Thymine, and Guanine - Cytosine. Thus, the pyrimidine bases present in DNA are thymine and cytosine.
WebIn DNA and RNA, refers to the linear sequence of base pairs or amino acids in a polynucleotide chain. Purine One of two categories of nitrogen base ring compounds found in DNA and RNA. A purine is a nine-membered double ring composed of one five-membered joined to a six membered ring containing four nitrogens. See pyrimidine.
